Abstract

PROBLEM TO BE SOLVED: To lower a ratio of unnecessary digital information contained in search results.SOLUTION: One or more search spaces in which a searchable range is restricted are stored in a search space definition file 17. A search space setting server 1 transmits a list of search spaces to a Web page display unit 21. The Web page display unit 21 displays the received list of the search spaces on a display device 27. The search space setting server 1 causes a search server 3 to search for digital information contained in a search space selected by an operator of a client 2. The search space setting server 1 associates digital information selected from among search results by the operator of the client 2 with the search space and stores the digital information in a report file 18. When the report file 18 exists, the search space setting server 1 searches both of the search space and the report file 18, and the Web page display unit 21 displays both of the search results on the display unit 27.

Description

  The present invention sets a range to be searched according to a search purpose or the like in advance as a virtual search space (VSS: Virtual Search Space), and makes it possible to search within the search space And a search system using the same.

  In recent years, digitization of information has been progressing rapidly. In the past, the centralization of digitization is to store data that is referred to when a computer system such as a bank account or resident's card of a company, government, etc. executes a basic business in a file or database (Data Base). there were.

On the other hand, various documents created in daily operations in organizations such as companies are stored as document files, table files, databases, etc. in each employee's client PC (Personal Computer), and are attached as e-mail attachments. It is transmitted to other client PCs or stored in the file server as shared information for the entire organization. The document file stored in the file server is referred to by various employees, and is sometimes copied and updated on the client PC.
In this manner, a large amount of document files, table files, e-mails, databases, records stored in the databases, programs, etc. (hereinafter collectively referred to as “files”) are distributed and stored in various computers. There will be many duplicate or similar files in your organization. In addition, the storage capacity of each computer continues to increase.

On the other hand, there are many cases where it is desired to refer to a file whose storage location is unknown, for example, a file created once by an employee who has already retired is required in the organization. In such a case, a method of specifying a keyword or file creator that should be included in the file and searching for a file including the specified keyword is widely performed.
However, when trying to search for files from all computers in the organization, a lot of unnecessary files that happened to match the keywords happened to be searched. Often you have to find the files you need.

  In this way, a large number of files are created and the searchable range is expanded, so there is a high possibility that the necessary files exist somewhere, but conversely, it becomes difficult to find the necessary files. Go. Further, as a result of the increase in the storage capacity of the computer, it is difficult to find a necessary file even when the search target is limited to one computer.

  In order to solve such a problem, a technique for limiting files to be searched is known. For example, in the search range determination method disclosed in Patent Document 1, sampling search (preliminary search) is first performed for each searchable database using a predetermined keyword, and a specified search condition is set. Predict the number of searches when searching each database with. And based on this prediction, a search object database is determined so that the number of searches may be below a predetermined number. That is, in this search range determination method, the search target is dynamically determined.

JP 2000-99514 A

However, although the search range determination method disclosed in Patent Document 1 can narrow down the search results by narrowing down the search target, whether or not the necessary files are included in the narrowed search results is completely considered. Not.
Here, when the nature of the problem is examined again, the large number of search results is not a problem, but rather desirable. In general, search results contain more unnecessary files than necessary files, and as a result, when there are many search results, the problem is that many unnecessary files are included in the search results. . That is, reducing the ratio of unnecessary document files included in the search results is an appropriate approach for solving the problem.

The search target of the search system according to each embodiment of the present invention is a document file, a table file, an electronic mail, a database (DB), each record stored in the DB, a program, etc. In the following description, these will be collectively referred to as “files”.
Hereinafter, a search system according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows an example of the configuration of a search system according to the first embodiment of the present invention.
<Configuration and function of the entire search system>
The search system according to the first embodiment includes a search space setting server 1, a search server 3, a file server 4, and a client 2.
The search space setting server 1, the search server 3, the file server 4, and the client 2 (hereinafter referred to as “server etc.”) can communicate with each other via a wired or wireless communication line such as a LAN (Local Area Network) 9. It is connected to the.
In FIG. 1, servers and the like are communicably connected via a LAN 9, but the connection method is not limited to a LAN, and may be connected by, for example, a WAN (Wide Area Network) or the Internet. In FIG. 1, servers and the like are connected to the same LAN segment. However, this configuration is merely an example, and any configuration may be used.

  Further, in FIG. 1, one search space setting server 1, search server 3, file server 4, and client 2 each exist, but two or more each may exist. The search space setting server 1, the search server 3, the file server 4, and the client 2 do not have to be different devices. For example, the search space setting server 1, the search server 3, and the file server 4 The function of the client 2 can also be realized by a single device.

  With the configuration described above, the client 2 can transmit a file search request to the file server 4 via the search space setting server 1 and the search server 3. Further, the file server 1 sends the file search result data to the client 2 via the search server 3 and the search space setting server 1, that is, the file name, URL, etc. of the file matching the search condition (hereinafter abbreviated as “search result data”). .) Can be sent.

<Configuration and function of client 2>
The client 2 is a computer and includes an input device 26, a display device 27, and a storage device 28.
The input device 26 includes a keyboard, a mouse, and the like. The operator of the client 2 can instruct a process to be executed by the client 2 by operating the input device 26. That is, the input device 26 functions as input means for the client 2.
The display device 27 includes a liquid crystal display, a printer, and the like. The display device 27 displays or prints the result of processing executed by the client 2. That is, the display device 27 functions as a display unit and an output unit of the client 2.
The storage device 28 includes a magnetic disk or the like. The storage device 28 is built in the client 2 or connected externally. The storage device 28 and the main storage device of the client 2 (not shown) function as storage means of the client 2.

The client 2 includes a CPU (Central Processing Unit), a main storage device, and the like not shown. The storage device 28 stores a program such as a WEB browser. The function of the WEB browser and the like is realized by the CPU loading a program such as the WEB browser onto the main storage device and executing the instruction code.
Techniques related to program execution as described above are well known. Therefore, in the following description and drawings, the WEB browser is described as if there is hardware that executes processing realized by various programs, such as the WEB page display unit 21. It should be noted that each unit (for example, the WEB page display unit 21) can be configured by hardware.

The WEB page display unit 21 is a WEB browser as described above. The WEB page display unit 21 transmits a URL (Uniform Resource Locator) or the like input by the operator of the client 2 using the input device 26 to the search space setting server 1. Further, the WEB page display unit 21 displays a WEB page described in HTML (Hyper Text Markup Language) transmitted from the search space setting server 1 on the display device 27.
Here, an IP address for uniquely specifying a location on a communication line, an identification name corresponding to the IP address (hereinafter simply referred to as “identification name”), and the like are assigned to the server and the like. For this reason, for example, where the client 2 sends the IP address of the client 2 itself in addition to the URL to the IP address of the search space setting server 1, where should the search space setting server 1 send the WEB page? Is specified.

<Configuration / Function of Search Space Setting Server 1>
The search space setting server 1 is a computer and includes a storage device 16 and an input device (not shown).
The storage device 16 is a device such as a magnetic disk. The storage device 16 is built in the search space setting server 1 or connected externally. The storage device 16 and the main storage device of the search space setting server 1 (not shown) function as storage means of the search space setting server 1.
The input device includes a keyboard, a mouse, and the like, and accepts an operation by an operator of the search space setting server 1.

  The storage device 16 stores a search space definition file 17 and a report file 18. The search space definition file 17 stores one or more search spaces (that is, file paths, file types, etc. of files to be searched) in accordance with the search purpose. As will be described later, the search space setting server 1 transmits a search space list to the WEB page display unit 21, and the WEB page display unit 21 displays the received search space list on the display device 27. Then, the operator of the client 2 selects a search space that matches the search purpose from the displayed search space list.

The report file 18 stores search result data corresponding to the search space.
As will be described later, the search space can be set according to the search purpose, such as a space for searching for files related to a specific development project. Then, the operator of the client 2 searches for a file included in the search space using a search condition such as a keyword. The operator of the client 2 further selects a file that matches the purpose of the search space. The selected file is stored in the report file 18 in association with the search space. That is, a desired file included in the search space is recorded in the report file 18.

  As a result, files that match the purpose of the search space and the like are gradually accumulated in the report file 18. When the operator of the client 2 requests a search for a desired file, if the report file 18 exists, the search space setting server 1 searches both the search space and the report file 18. The client 2 displays each search result on the display device 27 on a separate screen. Thereby, the operator of the client 2 can obtain a search result with low noise from the report file 18 including the file taken in by the operator of the other client 2. On the other hand, the operator of the client 2 can newly search for a file that has a large noise in the search space but has not yet been captured in the report file 18.

The search space setting server 1 includes a WEB page transmission unit 11 (WEB server) and a search space setting unit 12 (search space setting program).
Similar to the client 2, the search space setting server 1 includes a CPU and a main storage device not shown. The storage device 16 stores various programs such as a WEB server and a search space setting program. Search management data 13 is stored in the main storage device.
When the CPU loads a program such as a WEB server and a search space setting program onto the main storage device and executes the instruction code, each function of the WEB page transmission unit 11 and the search space setting unit 12 is realized.

  The WEB page transmission unit 11 is a WEB server such as Apache (registered trademark). The WEB page transmission unit 11 refers to the URL received from the WEB page display unit 21, creates a WEB page written in HTML or the like, and transmits it to the WEB page display unit 21. The WEB page transmission unit 11 activates the search space setting unit 12 when the URL received from the WEB page display unit 21 includes predetermined information. The search space setting unit 12 creates a WEB page written in HTTP, such as a login screen, a search space selection screen, and a search screen, and delivers it to the WEB page transmission unit 11. The WEB page transmission unit 11 transmits the delivered WEB page to the WEB page display unit 21.

As will be described later, the search management data 13 stores, for each client 2, data for identifying the operator of the client 2, data indicating a search range to be searched by the search space setting unit 12, search result data, and the like. The As will be described later, the operator of the client 2 first logs into the search space setting unit 12. The operator of the client 2 designates a search space to be searched next, and performs a process such as search for the designated search space. The operator of the client 2 logs out when necessary operations are completed.
The operator of the client 2 inputs a user ID for identifying the operator at the time of login, but does not input the user ID after that. It is necessary to memorize it. Similarly, it is necessary to store data for identifying a search space to be a search target designated by the operator of the client 2 until logging out. The same applies to search result data and the like. Therefore, in the first embodiment, these data are stored in the search management data 13. It is also possible to transmit and receive necessary data between the web page display unit 21 and the web page transmission unit 11 in a timely manner by using a method other than storing in the search management data 13, for example, an HTTP (Hypertext Transfer Protocol) cookie. It is.

When creating the search screen, the search space setting unit 12 transmits the search keyword and data (information indicating the search range) specifying the file to be searched to the search server 3, and the search result received from the search server 3 Set the data in the search screen.
As described above, an IP address, an identification name, and the like for uniquely specifying a location on a communication line are assigned to a server or the like. For this reason, for example, the search space setting unit 12 transmits the IP address of the search space setting server 1 in addition to each data to the IP address of the search server 3, so that the search server 3 transmits the search result data to where. Specify whether it is okay.

<Configuration / Function of Search Server 3>
The search server 3 is a computer, and includes a CPU, a main storage device, a storage device, and the like (not shown) as with the client 2. The storage device 16 is a device such as a magnetic disk, and stores various programs such as a search program (search unit 31).
Each function of the search unit 31 and the like is realized by the CPU loading a program such as a search program onto the main storage device and executing the instruction code.

The search unit 31 searches for a file stored in the file server 4 using the search keyword received from the search space setting unit 12 and transmits search result data to the search space setting unit 12.
In the first embodiment, the search target of the search unit 31 is a file stored in the file server 4. For example, the search unit 31 may also store files stored in the search space setting server 1 and the client 2. It can also be configured to be a search target.

Further, it is a well-known technique to search for a file by the search unit 31 as described above. For this reason, how the search unit 31 specifically searches for a file will not be described in detail here. For example, the search unit 31 receives a file search command (for example, “SearchFile Keyword = 'projectX' ”: Search for files containing the keyword 'projectX',“ Filetype = 'doc' or 'txt' ”: Search for files with the file extension 'doc' or 'txt', etc.) Search should be performed. In other words, the search space setting unit 12 may create a command or the like that can be understood by the search unit 31 and transmit it to the search unit 31.
The file server 4 is provided with a search agent (program), the search unit 31 transmits a search command or the like to the search agent, and the search agent transmits search result data to the search unit 31. At this time, the search unit 31 transmits search commands and the like to the search agents of the plurality of file servers 4 in parallel, receives the search result data from each search agent in parallel, and combines the search result data into one. In summary, the search result data can be merged and transmitted to the search space setting unit 12.

Here, “parallel” means that a search command or the like is transmitted to the search agent of one file server 4 and waits until the search result data is received from the search agent. Instead of sending a search command or the like to the search agent, for example, by creating a thread corresponding to each search agent of the plurality of file servers 4, the search command or the like is sent to each search agent, and search result data is sent from each search agent. This means that file search by each search agent is performed independently.
As described above, an IP address, an identification name, and the like for uniquely specifying a location on a communication line are assigned to a server or the like. For this reason, for example, the search unit 31 transmits the IP address of the search server 3 in addition to the search keyword to the IP address of the file server 4, thereby indicating where the file server 4 should transmit the search result data. Can be specified.

<Configuration / Function of File Server 4>
The file server 4 is a computer. The file server 4 includes a storage device 46. The storage device 46 is a device such as a magnetic disk. The storage device 46 is built in the file server 4 or connected externally. The storage device 46 and the main storage device of the file server 4 (not shown) function as storage means of the file server 4.

Although only one storage device 46 is shown in FIG. 1, a plurality of storage devices 46 of various types such as a magnetic tape, a magnetic disk, and an optical disk can be connected. As is well known, for example, when the search unit 31 searches for a file stored in the file server 4, the search unit 31 searches the storage device 46 based on the logical volume name, the file path, and the like. Can be specified.
Similarly to the storage device 46, the storage device 16 and the storage device 28 can be configured by a plurality of devices of various types, and files can be specified by logical volume names, file paths, and the like. .

  A search target file 47 is stored in the storage device 46. Here, the search target file 47 does not indicate a specific file stored in the storage device 46 but indicates all files that can be searched. Therefore, the search target file 47 may be all the files stored in the storage device 46, or may be all files excluding highly confidential files such as system logs. The file server 4 receives a search command and the like from the search unit 31. Then, the file server 4 searches the file stored in the search target file 47 for a file that matches the search condition such as including a search keyword, and transmits the search result data to the search unit 31.

<Configuration of each file>
FIG. 2 shows an example of the data structure of the search space definition file 17.
The search space definition file 17 includes one or more search space definition records 170. The search space definition record 170 includes data items of a search space ID 171, a search space name 172, a user ID 174, a password 175, and a search target 176. The user ID 174 and the password 175 are collectively referred to as a user-specific login authority 173, and are set for each search space ID 171 by the number of users having the login authority (m).

In the search space ID 171, an ID (Identifier) for the search space setting unit 12 or the like to identify the search space is set. Although not shown, the search space setting server 1 has a search space definition file creation / update program. An operator of the search space setting server 1 activates a search space definition file creation / update program by operating an input device (not shown) such as a keyboard and a mouse connected to the search space setting server 1.
The CPU of the search space setting server 1 executes the search space definition file creation / update program, thereby realizing the function of the search space definition file creation / update unit.
The search space definition file creation / update unit creates, changes, and deletes the search space definition record 170 based on each data input by the operator of the search space setting server 1. Then, the search space definition file creation / update unit sets a value input by the operator of the search space setting server 1, for example, “VSS1”, in the search space ID 171.

In the search space name 172, the name of the search space corresponding to the search space ID 171 is set. Specifically, the search space definition file creation / update unit sets a value input by the operator of the search space setting server 1, for example, “development project X”.
The name of the search space preferably represents the purpose of the search. As will be described later, the name set in the search space name 172 is displayed on the search space list screen, so that the operator of the client 2 searches for a file whose search space ID 171 “VSS1” is related to “development project X”. That is, the purpose of the search space.
Note that the search space definition record 170 includes, for example, “search purpose” as a data item in addition to the search space name 172, and the data item “search purpose” uses the search space ID 171 as a search purpose (for example, “technology related to the development project X”). Search for target data ") may be set. In this way, the operator of the client 2 can more easily select an appropriate search space by looking at the search purpose displayed on the search space list screen.

The user ID 174 is set with an ID that identifies a user who can search in the search space ID 171, that is, a user who can log in to the search space ID 171. Specifically, the search space definition file creation / update unit sets a value input by the operator of the search space map server 1, for example, “USR1” as the user ID 174.
In the password 175, a password to be input when the operator of the client 2 inputs the user ID 174 and logs in to the search space of the search space ID 171 is set.
In the search target 176, a file path, a file type, a keyword, and the like to be searched in the search space ID 171 are set. The setting contents of the search target 176 will be described in detail with reference to FIGS.

FIG. 3 shows an example of the concept of the search space. FIG. 3 shows an example in which a storage area of a predetermined storage device is set as a search space and the storage area of the storage device that can search for a file is limited.
In the search space shown in FIG. 3, the identification name of a certain file server 4 is “Server1”, and the identification name of another file server 4 is “Server2”. “Server1” is composed of two logical volumes, and each logical volume can be uniquely identified by the names “vol1” and “vol2”, respectively. “Server2” is composed of logical volumes that can be uniquely identified by the name of “vol1”.

“Vol1”, “vol2” of “Server1”, and “vol1” of “Server2” have file paths including folders and files as illustrated.
For example, “vol1” of “Server1” has two folders “etc” and “doc”. There are two files “file1.doc” and “file2.xml” in the “etc” folder, and one file “file3.doc” in the “doc” folder. Similarly, one folder “pjt” exists in “vol2” of “Server1”. In the “pjt” folder, there are three folders “pjt1”, “pjt2”, and “pjt3”. There are two files “file4.txt” and “file5.doc” in the “pjt1” folder.
In addition, one folder “usr” exists in “vol1” of “Server2”. In the “usr” folder, there are three folders “usr1”, “usr2”, and “usr3”. There is one “file5.doc” file in the “usr2” folder.

Of the above file server 4, logical volume, and file path, for example, it is assumed that a file related to the development project X exists only within the dotted line indicated by “VS301” in FIG. In this case, for example, a search space definition record 170 having a search space ID 171 of “VSS1” is created, and “Server1 / vol1 / doc /”, “Server1 / vol2 / pjt / pjt1” are stored in the search target 176 of the search space definition record 170. "/" And "Server2 / vol1 / usr /" should be set.
When such a search space definition record 170 is created and the operator of the client 2 is logged in to “VSS1”, the search space setting unit 12 sends only the files in the VS 301 of FIG. Is to be searched. That is, the search space setting unit 12 instructs to search only the files in “Server1 / vol1 / doc /”, “Server1 / vol2 / pjt / pjt1 /”, and “Server2 / vol1 / usr /”. To do.

In this example, the identification name, logical volume, and file path of the file server 4 are set in the search target 176. However, the search space setting server 1 such as a server other than the file server 4 is similarly searched. Can be set as a target. In addition to searching for the set identification name, logical volume, and file path of the server, for example, when “ALLOW Server1 / vol1 / doc /” is set, “Server1 / vol1 / doc /” is searched. When the target is set to “DENY Server1 / vol1 / doc /”, it is also possible to specify a combination of search target and non-search target, such as “Server1 / vol1 / doc /” excluded from the search target. It is.
Further, the search target 176 may be set with a file path, a file type, a keyword, and the like to be searched, or may be set in combination.

FIG. 4 shows another example of the concept of search space. FIG. 4 shows an example in which a file type is designated for the search target 176. FIG. 4 shows an example in which a predetermined file type is set in the search space and the types of files that can be searched are limited.
In FIG. 4, the configuration of the file server 4, logical volume, and file path is the same as in FIG. In the example of FIG. 4, a document file and a text file may be set as search targets, but it is assumed that the search location of the file cannot be specified. In this case, data indicating the file type of the document file and the text file, for example, “doc” and “txt” as file extensions may be set in the search target 176.
In this way, for example, a search unit 31 that does not have a search function by a file extension, that is, a search unit 31 that cannot specify a search target by a file extension, is searched without specifying a file extension. The search space setting unit 12 can select the search result data transmitted from the search unit 31 with the file extension “doc” or “txt”.

On the other hand, instead of simply setting data indicating the file type, for example, “Filetype = 'doc'
Or, the part of the file search command that specifies the search target may be set as it is, such as “txt”.
In this way, for example, the search unit 31 having a search function based on the file extension, that is, the search unit 31 capable of specifying the search target by the file extension is set as the search target 176. Search can be performed by creating a file search command using the data as it is. Furthermore, for example, “SearchFile (Keyword = 'projectX'and (Filetype =' doc 'or' txt '))" (files that contain the keyword' projectX 'and whose file extension is'doc' or 'txt' For example, it is possible to easily set a plurality of search conditions in combination.
As described above, the operator of the search space setting server 1 can create the search space definition record 170 according to the search purpose such as “search for files related to the development project X”.

FIG. 5 shows an example of the data structure of the report file 18.
The report file 18 is composed of one or more report records 180. The report record 180 is a record that stores search result data obtained by the search space setting unit 12. The report record 180 stores search result data received from the search unit 31 by the search space setting unit 12. More precisely, the search result data received by the search space setting unit 12 from the search unit 31 is displayed on the display device 27 of the client 2 as will be described later. Then, among the search result data displayed by the operator of the client 2, the data to be stored in the report record 180 is selected, and the client 2 transmits the selected search result data to the search space setting server 1. The search space setting unit 12 creates a report record 180 based on the transmitted search result data.
The report record 180 includes data items of a report ID 181, a report name 182, a search space ID 183, and a search result 184. There are one or more (n) search results 184.

In the report ID 181, an ID capable of uniquely identifying the report record 180 is set as “report01”. For example, although not shown, a counter having 0 as an initial value is stored in the storage device 16. Then, each time the report space 180 is created, the search space setting unit 12 increments the counter value by 1 and connects it to “report” to set the report ID 181.
For the report name 182, the name of the report record 180 is set, for example, “development plan”.
The search space ID 183 is set with the search space ID 171 of the search space to be searched, for example “VSS1”.
In the search result 184, the contents of the file itself, the file name, the URL of the file, and the like received by the search space setting unit 12 as the search result data from the search unit 31 are set. For example, by setting HTML format data including a file name and a URL, it is possible to display the data as it is as a part of a WEB page.

FIG. 6 shows an example of the data structure of the search management data 13. The search management data 13 is composed of zero or more search management records 130.
The search management record 130 is used by the search space setting unit 12 to specify the operator and search space of the client 2 until the operator of the client 2 logs in to the search space setting unit 12 and logs out. It is done. As will be described later, when the operator of the client 2 logs into the search space setting unit 12, the search space setting unit 12 creates a search management record 130 for the client 2. When the operator of the client 2 logs out from the search space setting unit 12, the search space setting unit 12 deletes the search management record 130 for the client 2. Therefore, if no operator of the client 2 is logged in to the search space setting unit 12, the search management record 130 does not exist (in other words, 0 exists).

The search management record 130 includes data items of a client identification 131, a search space ID 132, a user ID 133, a report search result 134, and a search space search result 135.
In the client identification 131, data capable of uniquely identifying the client 2, such as the IP address of the client 2, is set.
The search space ID 132 is set to the search space ID 171 of the search space where the operator of the client 2 is logged in, for example, “VSS1”.
In the user ID 133, the user ID 174 of the operator who has logged in the search space of the search space ID 132 is set.
In the report search result 134, search result data obtained by searching the report file 18, that is, the report ID 181 and the report name 182 of the report record 180 that matches the search condition are set.
The search space search result 135 is set with search result data obtained by searching the search space, that is, the file name, URL, etc. of the file that matches the search condition.
The description of the configuration and functions of the search system according to the first embodiment has been completed, and the operation of the search system according to the first embodiment will be described below.

<Operation of search system>
FIG. 7 is a flowchart showing an example of the operation of the WEB page display unit 21 related to file search.
<Process up to S710 in FIG. 7>
When the operator of the client 2 operates the input device 26 to activate the WEB page display unit 21, the WEB page display unit 21 displays a WEB browsing screen on the display device 27. Then, the operator of the client 2 operates the input device 26 to enter a predetermined URL (for example, “http://vsserver.somecompany.com/vssearch/rogin.html”) in the URL input / display field of the web browsing screen. When input, the WEB page display unit 21 transmits the input URL to the search space setting server 1. When receiving the transmitted URL, the WEB page transmission unit 11 of the search space setting server 1 transmits a WEB page for a login screen to the WEB page display unit 21. The WEB page display unit 21 displays the received WEB page on the display device 27 as a login screen. A display example of the login screen is shown in FIG.
In the following screen display examples including FIG. 8, the fields provided in the display screen of a normal WEB browser, such as the URL input / display field and the “return” button, are not displayed. Are naturally displayed on the screen.

<Login process (process related to S710 in FIG. 7)>
When the operator of the client 2 operates the input device 26 to input the user ID (G81) and password (G82) of the login screen and clicks the execution button at the bottom of the login screen, the WEB page display unit 21 is input. The user ID and password are transmitted to the WEB page transmission unit 11 together with the login process request. As a method of transmitting the login processing request, a predetermined URL (for example, “http://vsserver.somecompany.com/vssearch/cgi/rogin.cgi”) that specifies a CGI (Common Gateway Interface) or the like to execute the login processing is used. ) Are transmitted to the WEB page transmitting unit 11, and various methods are known, and these methods may be selected and used. (End of S710)

A similar method can be used for a search space selection processing request or the like to be described later. In this case, for example, for a search space selection process request, a predetermined URL (for example, “http://vsserver.somecompany.com/vssearch/cgi/vsselect.cgi”) designating a CGI different from the login process request is sent to the WEB page transmission unit. 11, the search space setting unit 12 can execute the search space selection process instead of the login process. That is, in this case, the search space setting program (search space setting unit 12) is composed of a plurality of CGIs.
Further, a parameter (“function = rogin” in this example) can be added to the CGI specification, such as “http://vsserver.somecompany.com/vssearch/cgi/vssearch.cgi&function=rogin”. By doing in this way, it becomes possible to perform different processes depending on the parameters for one CGI.

FIG. 16 is a flowchart illustrating an example of the operation of the search space setting unit 12 during the login process, that is, when the WEB page transmission unit 11 receives a login process request from the WEB page display unit 21.
When receiving a login processing request from the WEB page display unit 21, the WEB page transmission unit 11 activates the search space setting unit 12.
The search space setting unit 12 determines whether the combination of the user ID and the password transmitted by the WEB page transmission unit 11 is correct. That is, it is determined whether it matches any one of the login authority 173 for each user (S1610).
When the combination of user ID and password does not match the login authority 173 for each user of any search space definition record 170 (S1610: NO), the search space setting unit 12 creates an error screen (S1630) and ends the process. To do. In the following description including this error screen, “the search space setting unit 12 creates the X screen” means that the search space setting unit 12 is displayed on the display device 27 by the WEB page display unit 21. The creation of a WEB page made up of, etc.

  When the combination of the user ID and the password matches any of the login authority 173 for each user of the search space definition record 170 (S1610: YES), the search space setting unit 12 has two or more corresponding search spaces. That is, it is determined whether the combination of the user ID and the password matches any of the login authority 173 for each user for the plurality of search space definition records 170 (S1620). When there are two or more corresponding search spaces (S1620: YES), the search space setting unit 12 creates a search space selection screen (S1640). On the other hand, when there is only one corresponding search space (S1620: NO), the search space setting unit 12 creates a search screen (S1650).

  When creating a search space selection screen (S 1640), the search space setting unit 12 includes the user ID and password received from the WEB page display unit 21 by any of the user-specific login authorities 173 in the search space definition record 170. The search space ID 171 and the search space name 172 of the record that matches the combination are set as part of the WEB page. As a result, the search device 27 of the client 2 displays all the search spaces in which the operator of the client 2 can log in, as indicated by G91 in FIG. 9, and the operator of the client 2 displays the displayed search space name. With reference to 172, a search space ID 171 suitable for the purpose can be selected.

  When creating a search space selection screen (S1640), the search space setting unit 12 creates a search management record 130 for the client 2 of the WEB page display unit 21 that has transmitted the login processing request. Specifically, the search space setting unit 12 sets the data (such as the IP address of the client 2) that can identify the client 2 that transmitted the login processing request in the client identification 131, and has received it from the WEB page display unit 21 The user ID is set to the user ID 133. Then, the search space setting unit 12 sets data indicating that a value to be set is not yet determined, such as a blank value (space), in the search space ID 132, the report search result 134, and the search space search result 135 ( Hereinafter, description will be made on the assumption that the IP address of the client 2 is set in the client identification 131 and a space is set in the search space ID 132, the report search result 134, and the search space search result 135). Therefore, in the subsequent processing, the search space setting unit 12 knows the operator of the processing target client 2 by referring to the user ID 133, and the space is set in the search space ID 132, so that the client 2 Thus, it can be known that the search space for the user ID 133 is not fixed.

  When creating a search screen (S 1650), the search space setting unit 12 matches the combination of the user ID and password received from the client 2 by any of the user-specific login authorities 173 in the search space definition record 170. The search space ID 171 and the search space name 172 of the record are set in the WEB page. As a result, the display device 27 of the client 2 displays the search space ID and the search space name to which the operator of the client 2 is logged in as shown in the upper left part of the screen of FIG. , It is possible to confirm what kind of search the user is logged into the search space of the search space ID 171 suitable for.

  When creating a search screen (S1650), the search space setting unit 12 creates a search management record 130 for the client 2 of the WEB page display unit 21 that has transmitted the login processing request. Specifically, the search space setting unit 12 sets data (such as the IP address of the client 2) that can identify the client 2 that has transmitted the login processing request in the client identification 131, and sets any of the login authority 173 for each user. The search space ID 171 of the record that matches the combination of the user ID and password received from the client 2 is set as the search space ID 132, and the user ID received from the WEB page display unit 21 is set as the user ID 133. Then, the search space setting unit 12 sets data indicating that a value to be set, such as a blank value (space), has not yet been determined in the report search result 134 and the search space search result 135 (hereinafter, client The explanation is made on the assumption that the IP address of the client 2 is set in the identification 131 and a space is set in the report search result 134 and the search space search result 135). Therefore, in the subsequent processing, the search space setting unit 12 knows the operator of the processing target client 2 by referring to the user ID 133 and also refers to the processing space client 132 and the user ID 133 by referring to the search space ID 132. You can know the search space for.

  The search space setting unit 12 ends the process when a search space selection screen or a search screen is created. The error screen, search space selection screen, search screen, that is, the WEB page of each screen created by the search space setting unit 12 is transmitted to the WEB page display unit 21 by the WEB page transmission unit 11.

<Search space selection process (process related to S720 in FIG. 7)>
Here, the operation of the WEB page display unit 21 will be described using FIG. 7 again.
The WEB page display unit 21 displays the WEB page received from the search space setting unit 12 on the display device 27. Therefore, when the WEB page display unit 21 receives the WEB page of the error screen from the search space setting unit 12, the error screen is displayed on the display device 27. In this case, the operator of the client 2 may solve the cause of the error and perform the login operation again. When the login operation is performed, the WEB page display unit 21 performs the login process in step S710 again.

When the WEB page display unit 21 receives the WEB page of the search screen from the search space setting unit 12, the search screen is displayed on the display device 27, and the operator of the client 2 can perform the search operation. The operation of the WEB page display unit 21 and the like related to the search operation will be described later as search processing (S740 and the like).
When the WEB page display unit 21 receives the WEB page of the search space selection screen from the search space setting unit 12, the search space selection screen is displayed on the display device 27, and the operator of the client 2 performs the search space selection operation. be able to.

A display example of the search space selection screen is shown in FIG. As shown in FIG. 9, the search space selection unit (G91) of the search space selection screen has radio buttons, search space IDs, search space names, and search space names for all search spaces into which the operator of the client 2 can log in. Is displayed. The operator of the client 2 can select a search space to be searched with reference to the displayed search space name. FIG. 9 illustrates a state where “VSS1” is selected.
When the operator of the client 2 clicks the radio button of the search space to be searched using the input device 26, activates the radio button and clicks the execute button in the lower right part of the search space selection screen, the WEB The page display unit 21 transmits the search space ID corresponding to the activated radio button to the WEB page transmission unit 11 together with the search space selection processing request.

  On the other hand, when the operator of the client 2 clicks the cancel button in the lower right part of the search space selection screen, the WEB page display unit 21 transmits a logout processing request to the WEB page transmission unit 11. The operation of the search space setting unit 12 and the like related to the logout operation will be described later as logout processing (S750 and the like). (S720)

FIG. 17 is a flowchart showing the operation of the search space setting unit 12 during the search space selection process, that is, when the WEB page transmission unit 11 receives a search space selection process request from the WEB page display unit 21.
When receiving a search space selection processing request from the WEB page display unit 21, the WEB page transmission unit 11 activates the search space setting unit 12.
The search space setting unit 12 determines whether the operator of the client 2 can search the selected search space (S1710). Specifically, first, the user ID 133 of the search management record 130 in which the IP address of the client 2 of the WEB page display unit 21 that transmitted the search space selection processing request matches the client identification 131 is referred to. Then, it is determined whether any of the user IDs 174 of the search space definition record 170 in which the search space ID and the search space ID 171 received by the WEB page transmission unit 11 match the user ID 133. The search space setting unit 12 determines that the selected search space can be searched if they match (S1710: YES), and determines that the selected search space cannot be searched if they do not match (S1710: NO).

  It should be noted that the description “the user ID 133 of the search management record 130 in which the IP address of the client 2 of the WEB page display unit 21 that transmitted the search space selection processing request and the client identification 131 match” as described above is accurate. Since it is redundant and difficult to understand, it will be described simply as “target search management record 130” or “target user ID 133” in the following description. Similarly, the description “user ID 174 of the search space definition record 170 in which the search space ID received by the WEB page transmission unit 11 and the search space ID 171 match” is simply “target search space definition record 170”, “target user”. It is described as “ID174”.

If the search space setting unit 12 determines that the selected search space is not searchable (S1710: NO), it creates an error screen (S1720) and ends the process.
On the other hand, when it is determined that the selected search space can be searched (S1710: YES), the search space setting unit 12 creates a search screen (S1730) and ends the process.
When creating the search screen (S1730), the search space setting unit 12 sets the target search space ID 171 and the target search space name 172 in the WEB page. As a result, the display device 27 of the client 2 displays the search space ID and the search space name to which the operator of the client 2 is logged in as shown in the upper left part of the screen of FIG. , It is possible to confirm whether the user is logged in to the search space ID 171 suitable for the search.

When creating a search screen (S1730), the search space setting unit 12 sets the search space ID received from the client 2 to the search space ID 132 of the target search management record 130. Therefore, in the subsequent processing, the search space setting unit 12 knows the operator of the processing target client 2 by referring to the user ID 133, and the operator of the processing target client 2 by referring to the search space ID 132 You can know the search space where you are logged in.
The search space setting unit 12 ends the process when a search space selection screen or a search screen is created. Then, the error screen and search screen created by the search space setting unit 12, that is, the WEB page of each screen, is transmitted to the WEB page display unit 21 by the WEB page transmission unit 11.

<Search processing, display processing, report creation processing (processing related to S730 and S740 in FIG. 7)>
Here, the operation of the WEB page display unit 21 will be described using FIG. 7 again. The WEB page display unit 21 displays the WEB page received from the search space setting unit 12 on the display device 27. Therefore, when the WEB page display unit 21 receives the WEB page of the error screen from the search space setting unit 12, the error screen is displayed on the display device 27. In this case, the operator of the client 2 may solve the cause of the error and perform the search space selection operation (S720) again. At this time, the WEB page display unit 21 performs the process of step S720 again.
When the WEB page display unit 21 receives the WEB page of the search screen from the search space setting unit 12, the search screen is displayed on the display device 27, and the operator of the client 2 can perform a search operation or the like.

A display example of the search screen is shown in FIG. As shown in FIG. 10, the search screen includes a search condition designation part (G101), a search result switching button (G102), a search result display part (G103), a “search” button, and an “end” button. Is displayed. Further, the search space ID (“VSS1”) and the search space name (“product X development project”) in which the operator of the client 2 is logged in are displayed in the upper left portion of the screen in the example of FIG.
When the operator of the client 2 clicks the end button (S730: YES), the WEB page display unit 21 transmits a logout processing request to the WEB page transmission unit 11 (S750). The operation of the search space setting unit 12 and the like related to the logout operation will be described later as logout processing.

  On the other hand, when the operator of the client 2 inputs the keyword of the search condition specifying unit (G101) and clicks the execution button (S730: NO), the WEB page display unit 21 displays the input keyword together with the search processing request on the WEB page. It transmits to the transmission part 11 (S740). In FIG. 10, only the keyword is shown as the search condition of the search condition specifying unit (G101), but there are various specifications such as whether the file is a document file, a table file, or an HTML file, the file update date, etc. Data can be used as a search condition.

Hereinafter, the process for step S740 in FIG. 7 will be described.
In the search space setting server 1, when a search process to be described later is completed, the WEB page transmission unit 11 transmits the WEB page of the search screen including the search result data to the WEB page display unit 21. The WEB page display unit 21 displays the received WEB page on the display device 27 as a search screen. At this time, as shown in FIG. 11, in the search result display part (G103) of the search screen, the file name (“product X development plan” etc.) and the file location (“Server1”) included in the search result data are displayed. / vol1 / doc / file3 ”etc.) is displayed. That is, in FIG. 11, in order to correspond to the description of the search space in FIGS. 3 and 4, the file location is indicated by the identification name, logical volume, and file path of the file server 4.
A technique for converting a URL received by the WEB page transmission unit 11 into another URL or the like is well known. For example, in FIG. 11, “http://Server1.vsserver.com/vol1/” is not used instead of “Server1 / vol1 / doc / file3” indicating the location of the file by the identification name, logical volume and file path of the file server 4. doc / file3 ”and the URL are displayed, and when the WEB page display unit 21 transmits“ http://Server1.vsserver.com/vol1/doc/file3 ”to the WEB page transmission unit 11,“ Server1 / vol1 / It can also be converted to doc / file3 ”.
In the following description, file locations and URLs as shown in FIG. 11 are collectively referred to as URLs.

<File content display processing request>
When the operator of the client 2 clicks a URL or the like displayed on the search result display unit (G103), the WEB page display unit 21 transmits the clicked URL or the like to the WEB page transmission unit 11 together with a file content display processing request.
In the search space setting server 1, when a display process described later is completed, the WEB page transmission unit 11 transmits a WEB page on the display screen including the contents of the file corresponding to the received URL or the like to the WEB page display unit 21. The WEB page display unit 21 displays the received WEB page on the display device 27 as a display screen.

A display example of the display screen is shown in FIG. As shown in FIG. 12, a file content display part (G121) and an “end” button are displayed on the display screen. In the example of FIG. 12, the search space ID (“VSS1”) in which the operator of the client 2 is logged in, the search space name (“product X development project”), and the file name displaying the file contents ( “Product X Development Plan”) is displayed in the upper left part of the screen.
When the operator of the client 2 clicks the end button on the display screen, the WEB page display unit 21 displays the search screen of FIG. 11 again. Therefore, the operator of the client 2 can confirm the file contents of each file by clicking the URL or the like displayed on the search result display unit (G103).

<Report creation processing request>
The operator of the client 2 can select all or part of the file displayed in the search result display part (G103) and store it in the report file 18. By storing the search result data in the report file 18, it is possible to eliminate the waste of performing the same search many times. Further, by selecting and storing only the files that match the search purpose from the search result data, for example, the search results can be shared within the same development project. In this way, a search result with low noise can be obtained from the report file 18. Furthermore, since the files that match the search purpose are gradually accumulated by the operators of the plurality of clients 2 in the report file 18, a search space that has a large amount and a small amount of noise as the report file 18 grows with time. Will go.

Specifically, when the search process is completed, the search result display part (G103) of the search screen not only displays the file name included in the search result data, but also as shown in FIG. A check box is displayed corresponding to each file name. Further, for example, as shown in FIG. 11, a “Create Report” button is displayed in the lower left part of the screen.
The operator of the client 2 uses the input device 26 to click on the check box of the file to be stored in the report file 18 and activates the check box. When the operator of the client 2 clicks the report creation button with the check box activated, the WEB page display unit 21 displays a report creation screen as shown in FIG.

As shown in FIG. 13, a report name input field (G131), a selection result display part (G132), a “Create” button, and an “End” button are displayed on the report creation screen. In the selection result display part (G132), the file name, URL, etc. selected by the check box among the file names, URLs, etc. displayed in the search result display part (G103) of the search screen are displayed. In the example of FIG. 13, the search space ID (“VSS1”) and the search space name (“product X development project”) in which the operator of the client 2 is logged in are displayed in the upper left portion of the screen.
The operator of the client 2 can confirm whether a necessary file has been selected by the selection result display part (G132) on the report creation screen. For example, when it is noticed that an unnecessary file has been selected, when the end button of the report creation screen is clicked, the WEB page display unit 21 displays the search screen of FIG. 11 again. Therefore, the operator of the client 2 can redo the file selection by clicking the check box.

On the other hand, when the operator of the client 2 inputs a report name (for example, “development plan”) to be created in the report name input field (G131) and clicks the creation button, the WEB page display unit 21 displays the report. The report name input in the name input field (G131) and the URL displayed in the selection result display section (G132) are transmitted to the WEB page transmission section 11 together with the report creation processing request.
In the search space map server 1, when a report creation process described later is completed, the WEB page transmission unit 11 transmits the WEB page of the search screen to the WEB page display unit 21. The WEB page display unit 21 displays the received WEB page on the display device 27 as a search screen as shown in FIG.

  In addition to inputting the report name, edit the file name of the search result data (for example, change "Product X Development Plan" to "Product X Development Plan (November 10, 2008 search version)") ) The search result data may be changed by adding a comment such as “It is a plan and different from the current plan” to the search result data.

<Report search result acquisition processing request>
In FIG. 11, when the operator of the client 2 clicks “report” of the search result switching button (G102), the WEB page display unit 21 transmits a report search result acquisition processing request to the WEB page transmission unit 11.
In the search space setting server 1, when a search result acquisition process described later ends, the WEB page transmission unit 11 transmits a WEB page of the search screen including the search result data to the WEB page display unit 21. The WEB page display unit 21 displays the received WEB page on the display device 27 as a search screen.

At this time, as shown in FIG. 14, in the search result display part (G103) of the search screen, the report name (such as “development plan”) and the report included in the search result data for which the report file 18 is to be searched. An ID (such as “report01”) is displayed.
As will be described later, in the search process of the search space setting unit 12, in addition to the search space selected in the search space selection process, the report file 18 is also a search target, and the search of the search space and the search of the report file 18 are performed in parallel. To be executed. The search space setting unit 12 stores the search result data for the search space in the search space search result 135 of the search management record 130 for the client 2, and stores the search result data for the report file 18 in the report search result 134. To do. Then, the search space setting unit 12 first transmits the WEB page of the search screen including the search result data for the search space to the WEB page display unit 21. As a result of this process, search result data for the search space is displayed in the search result display part (G103) of the search screen at the end of the search process, as shown in FIG. Then, the operator of the client 2 can view the search result data for the report file 18 by clicking “Report” of the search result switching button (G102).

  In addition, after clicking “report” of the search result switching button (G102) and further clicking “file” of the search result switching button (G102), the WEB page display unit 21 requests the search space search result acquisition process. Is transmitted to the WEB page transmission unit 11. Then, in the search space setting server 1, when the search result acquisition process described later is completed, the WEB page transmission unit 11 transmits the WEB page of the search screen including the search result data for the search space to the WEB page display unit 21. The WEB page display unit 21 displays the received WEB page on the display device 27 as a search screen. Through the above processing, the search screen as shown in FIG. 11 is displayed again on the display device 27.

As described above, the search space search results and report search results are not displayed on the same screen, but are displayed separately, so that the created report related to the specified keyword can be compared with the report search results (with low noise compared). You can search for it only in a small amount). In addition, when a file added to the search target file 47 is to be searched after the report is created, it can be searched only in the search space search result.
In other words, the search space is searched mainly for the purpose of searching for the resource from which the report is created, while the search of the report is performed for the purpose of searching for information that has already been scrutinized in relation to the keyword. The purpose is different. Thus, when searching for two or more different spaces for different purposes, it is preferable not to display the search results on the same screen but to display them separately on different screens.

<Report content display processing request>
In FIG. 14, when the operator of the client 2 clicks a report ID (such as “report01”) displayed in the search result display section (G103), the WEB page display section 21 requests the clicked report ID for a report content display processing request. At the same time, it is transmitted to the WEB page transmission unit 11.
In the search space setting server 1, when a display process described later is completed, the WEB page transmission unit 11 transmits a WEB page on the display screen including the content of the report corresponding to the received report ID to the WEB page display unit 21. The WEB page display unit 21 displays the received WEB page on the display device 27 as a display screen.

A display example of the display screen is shown in FIG. As shown in FIG. 15, a report content display part (G151) and an “end” button are displayed on the display screen. In the example of FIG. 15, the search space ID (“VSS1”) in which the operator of the client 2 is logged in, the search space name (“product X development project”), and the report name displaying the report contents ( “Development plan” is displayed in the upper left part of the screen.
When the operator of the client 2 clicks the end button on the display screen, the WEB page display unit 21 displays the search screen of FIG. 11 again. Therefore, the operator of the client 2 can confirm the report contents of each report by clicking the report ID displayed on the search result display unit (G103).

As will be described later, in each process of step S740, the WEB page display unit 21 may receive and display the WEB page of the error screen from the WEB page transmission unit 11.
This is the end of the description centered on the operation of the client 2 and the processing of the WEB page display unit 21. Thereafter, the WEB page display unit 21 performs a search process request, a file content display process request, a report content display process request, a report creation process request, a search space search result acquisition process request, a report search result acquisition process request, and a logout process request. The operation of the search space setting unit 12 in the case where is transmitted will be mainly described.

<Search processing: Processing when a search processing request is received>
FIG. 18 is a flowchart illustrating an example of the operation of the search space setting unit 12 during search processing. When receiving a search processing request from the WEB page display unit 21, the WEB page transmission unit 11 activates the search space setting unit 12.
The search space setting unit 12 performs search space search (S1810) and report file 18 search (S1820) in parallel.
Here, “parallel” means that, for example, the search of the report file 18 is first performed (S1820), and then the search of the virtual search space is not performed (S1810), but the search of the report file 18 is performed (S1820). By creating a thread corresponding to each search of the search space (S1810), it means that the search of the report file 18 (S1820) and the search of the search space (S1810) are performed independently.

  Specifically, for the search of the search space (S1810), the search space setting unit 12 searches the search space from the search management record 130 (target search management record 130) for the client 2 of the WEB page display unit 21 that has transmitted the search processing request. ID 132 (target search space ID 132) is acquired. Then, the search space setting unit 12 creates a search command based on the search keyword received from the search target 176 of the search space definition record 170 in which the target search space ID 132 and the search space ID 171 match, and the WEB page display unit 21. It transmits to the part 31.

  Further, specifically for the search of the report file 18 (S1820), the search space setting unit 12 receives from the WEB page display unit 21 the search result 184 of the report record 180 in which the target search space ID 132 matches the search space ID 183. It is determined whether or not the searched keyword is included. When the search keyword is included in the search result 184, the search space setting unit 12 acquires the report ID 181 and the report name 182 of the report record 180 including the search keyword.

  When receiving the search result data from the search unit 31, the search space setting unit 12 sets the search result data in the search space search result 135 of the target search management record 130. In addition, the report ID 181 and the report name 182 acquired from the report record 180 in the process of step S1820 are set in the report search result 134. (S1830)

Next, the search space setting unit 12 creates a search result screen (S1840) and ends the process.
When creating the search result screen (S1840), the search space setting unit 12 sets the file name, URL, etc. included in the search result data received from the search unit 31 in the WEB page.
For the search space search (S1810), the search space setting unit 12 transmits search result data from the search unit 31 for a predetermined time (for example, 1 second) after transmitting the search command to the search unit 31. If the predetermined time is exceeded, it may be determined that the search has failed due to a communication line abnormality or the like. Further, when the search space setting unit 12 determines that the search has failed, the search space setting unit 12 may perform the search again a predetermined number of times (for example, three times).

  Furthermore, even if it is determined that the search space search (S1810) has failed due to a predetermined number of searches failing or the like, if the search of the report file 18 (S1820) is successful, the report search result 134 is displayed. The WEB page in which the file name, URL, etc. are not set may be created as a search screen. In this way, the operator of the client 2 clicks on “report” of the search result switching button (G102) on the search screen, so that only the search result data (for example, the contents of the file itself) about the report file 18 is displayed. Can see.

  Conversely, when the search of the report file 18 (S1820) fails due to a failure of the storage device 16 and the search of the search space is successful (S1810), the search space search result 135 is set and received from the search unit 31. The search screen may be created by setting the file name, URL, etc. included in the search result data to the WEB page. By doing so, the operator of the client 2 can see only the search result data for the search space.

On the other hand, if either one of the search space search (S1810) or the report file 18 search (S1820) fails, the search space setting unit 12 may create an error screen and terminate the process. In this way, the operator of the client 2 can determine that all search processes have been performed normally when the search screen is displayed.
The error screen and search screen created by the search space setting unit 12, that is, the WEB page of each screen is transmitted to the WEB page display unit 21 by the WEB page transmission unit 11. A screen is displayed.

  As described above, the search of the search space and the search of the report file 18 are performed in parallel, so that compared to the case where the search of the search space and the search of the report file 18 are sequentially performed, from the start of search to the end of both searches. The processing time can be shortened. However, since the search of the report file 18 can be performed without sending a large amount of data transmission / reception such as transmission of a search command to the search unit 31 and reception of search result data from the search unit 31, it is generally compared with search of the search space. And finish in a short time. That is, the processing time required for searching the report file 18 is generally negligible with respect to the processing time required for searching the search space. Accordingly, the search space may be searched first, and then the report file 18 may be searched sequentially after the search space search has been completed normally. In this way, when the search of the search space does not end normally due to a communication error or the like, the search of the report file 18 can be prevented and unnecessary search processing can be avoided.

  That is, what is important is that search space search is performed only when a search request for search space is received, and only search of report file 18 is performed when a search request for report file 18 is received. The search of the report file 18 is not performed at another search request timing, but when the search space search processing request is received from the WEB page display unit 21, the search of the search space and the search of the report file 18 are performed simultaneously (same search) To do at the request timing). By doing so, it is possible to display the search result of the report file 18 that is consistent with the search result of the search space.

<Search result acquisition processing: processing when a search space search result acquisition processing request or report search result acquisition processing request is received>
FIG. 19 is a flowchart illustrating an example of the operation of the search space setting unit 12 during the search result acquisition process. When receiving a search processing request from the WEB page display unit 21, the WEB page transmission unit 11 activates the search space setting unit 12.
The search space setting unit 12 determines whether or not the processing request transmitted from the WEB page display unit 21 is a search space search result acquisition processing request (S1910). When it is a search space search result acquisition processing request (S1910: YES), the search space setting unit 12 creates a search result screen for the search space (S1920). On the other hand, when it is not a search space search result acquisition process request, that is, when it is a report search result acquisition process request (S1910: NO), the search space setting unit 12 creates a search result screen for the report file 18 (S1930).
The search space setting unit 12 creates a search result screen for the search space or a search result screen for the report file 18, and then ends the process.

When creating a search result screen for the search space (S1920), the search space setting unit 12 searches the search space from the search management record 130 for the client 2 of the WEB page display unit 21 that has transmitted the search space search result acquisition processing request. The result 135 (target search space search result 135) is acquired, and the file name, URL, etc. included in the target search space search result 135 are set in the WEB page.
When creating a search result screen for the report file 18 (S1930), the search space setting unit 12 searches for a report from the search management record 130 for the client 2 of the WEB page display unit 21 that has transmitted the search space search result acquisition processing request. The result 134 (target report search result 134) is acquired, and the report name and report ID included in the target report search result 134 are set in the WEB page.

  The search (result) screen created by the search space setting unit 12, that is, the WEB page of the search (result) screen is transmitted to the WEB page display unit 21 by the WEB page transmission unit 11. As a result, when the WEB page display unit 21 transmits a search space search result acquisition processing request to the display device 27, a search screen as shown in FIG. 11 is displayed, and the WEB page display unit 21 acquires the report search result. When the processing request is transmitted, a search screen as shown in FIG. 14 is displayed.

As described with reference to FIG. 18, when the WEB page transmission unit 11 receives a search processing request from the WEB page display unit 21, both the search space and the report file 18 are searched at the same time, and each search result is searched for the search space. The search result 135 and the report search result 134 are stored.
Then, when the operator of the client 2 clicks “file” of the search result switching button (G102), the search result stored in the search space search result 135 is displayed without searching the search space again, and “report” is displayed. When clicked, the search result stored in the report search result 134 is displayed without searching the report file 18 again.
That is, by searching the search space and the report file 18 at the same time only when the search condition (G101) is newly specified and when the search condition (G101) is changed, both search results are stored. When the search result switching button (G102) is operated without changing the search condition (G101), a constant search result can always be displayed.
Therefore, for example, even when an operator of the client 2 newly performs a search by specifying a search condition (G101) and an operator of another client 2 adds a file to the search target file 47, the search space The display content of the search result screen for is not changed. Therefore, for example, the operator of the client 2 switches the display screen with the search result switching button (G102) while scrolling the search result screen for the search space and the search result screen for the report file 18, respectively, and displays both search results. Search results can be confirmed while comparing.

<Report creation processing: Processing when a report creation processing request is received>
FIG. 20 is a flowchart illustrating an example of the operation of the search space setting unit 12 during the report creation process. When receiving the report creation processing request from the WEB page display unit 21, the WEB page transmission unit 11 activates the search space setting unit 12.
The search space setting unit 12 creates a report record 180 (S2010).
Specifically, the search space setting unit 12 sets an ID for uniquely identifying the report record 180 such as “report01” in the report ID 181 and sets the report name received from the WEB page display unit 21 in the report name 182. To do.
The search space setting unit 12 acquires the search space ID 132 from the search management record 130 (target search management record 130) for the client 2 of the WEB page display unit 21 that has transmitted the report creation processing request, and sets the search space ID 132 as the search space ID 183. To do.

Further, the search space setting unit 12 acquires the search space search result 135 (target search space search result 135) from the target search management record 130, and the content of the file itself included in the target search space search result 135, its file name, The contents of the file itself corresponding to the URL received from the WEB page display unit 21 and the file name are obtained from the URL of the file. Then, the search space setting unit 12 stores the URL received from the WEB page display unit 21 and the contents of the acquired file itself and the file name in the search result 184 by the number of URLs received from the WEB page display unit 21. Set.
When the number of URLs received from the WEB page display unit 21 is zero, that is, for example, in the search screen of FIG. 11, the check button of the search result display unit (G103) is not activated and the report creation button is clicked. When the creation button is clicked on the report creation screen of FIG. 13, the contents of the file itself, the file name, the URL of the file, etc. are not set in the search result 184. That is, in this case, the number of repetitions n of the search result 184 is zero.

The search space setting unit 12 stores the report record 180 in which the above data is set in the report file 18.
Next, the search space setting unit 12 creates a search screen (S2020) and ends the process. The content of the search screen creation process is the same as the search screen creation (S1730) of the search space selection process (FIG. 17) described above.
The search screen created by the search space setting unit 12, that is, the WEB page of the search screen is transmitted to the WEB page display unit 21 by the WEB page transmission unit 11. As a result, a search screen as shown in FIG. 10 is displayed on the display device 27.

<Display processing: Processing when a file content display processing request or a report content display processing request is received>
FIG. 21 is a flowchart illustrating an example of the operation of the search space setting unit 12 during display processing. When receiving the file content display processing request or the report content display processing request from the WEB page display unit 21, the WEB page transmission unit 11 activates the search space setting unit 12.
The search space setting unit 12 determines whether or not the processing request transmitted from the WEB page display unit 21 is a file content display processing request (S2110). If it is a file content display processing request (S2110: YES), the search space setting unit 12 acquires a file indicated by the URL received from the WEB page display unit 21 (S2120). Specifically, for example, when the URL or the like is “Server1 / vol1 / doc / file3”, the logical volume name of the file server 4 whose identification name is “Server1” is “vol1” via the LAN 9. Get the "/ doc / file3" file of the logical volume. Then, the contents of the file are edited into a WEB page to create a display screen (S2130), and the process ends.

  Note that the processing of steps S2120 and S2130 may be performed not by the search space setting unit 12 but by the WEB page transmission unit 11. In this case, the WEB page transmission unit 11 determines whether the URL received from the WEB page display unit 21 satisfies a predetermined condition before starting the search space setting unit 12 (for example, “reportX” (X is a numerical value of one digit or more)). Whether or not). Then, the WEB page transmission unit 11 activates the search space setting unit 12 when a predetermined condition is satisfied, and from the WEB page display unit 21 by a normal WEB server function when the predetermined condition is not satisfied. What is necessary is just to acquire the WEB page which received URL etc. show, and to transmit to the WEB page display part 21. FIG.

When it is not a file content display processing request, that is, when it is a report content display processing request (S2110: NO), the search space setting unit 12 generates a report record 180 in which the report ID received from the WEB page display unit 21 matches the report ID 181. Obtain (S2140). Then, the search space setting unit 12 creates a display screen by editing the data set in the search result 184 of the acquired report record 180, that is, the file name, URL, etc. into the WEB page (S2150), and ends the processing. To do.
If the number of repetitions n of the search result 184 of the acquired report record 180 is 0, that is, if no file name, URL, or the like is set in the search result 184, the search space setting unit 12 sets the file name, URL Create a display screen with no settings.

  The display screen created by the search space setting unit 12, that is, the WEB page of the display screen is transmitted to the WEB page display unit 21 by the WEB page transmission unit 11. As a result, when the WEB page display unit 21 transmits a file content display processing request to the display device 27, a display screen as shown in FIG. 12 is displayed, and the WEB page display unit 21 issues a report content display processing request. When transmitted, a display screen as shown in FIG. 15 is displayed.

In the above processing, if all the search results 184 set in the report record 180 are edited to the WEB page, the operator of the client 2 can know the URLs and the like of all the searched files. The existence of the file searched by the operator can also be known. This is desirable, for example, from the viewpoint of sharing information throughout the development project, but also leads to the location of a file without access authority being known.
Therefore, if security is important, in the processing of step S2540, it is determined whether or not the operator of the client 2 has access authority for the URL or the like for each search result 184. It is sufficient that the file name, URL, and the like of 184 are not set in the WEB page. In this case, the file name may be set and the URL or the like may not be set. In this way, it is possible to indicate that the file related to the search purpose exists while keeping the existence location of the file secret, so that the operator of the client 2 has the access authority for the file. It becomes possible to obtain information from the person.

<Logout processing: Processing when a logout processing request is received>
FIG. 22 is a flowchart illustrating an example of the operation of the search space setting unit 12 during logout processing.
When receiving the logout processing request from the WEB page display unit 21, the WEB page transmission unit 11 activates the search space setting unit 12. The search space setting unit 12 deletes the search management record 130 for the client 2 of the WEB page display unit 21 that has transmitted the login processing request, creates a logout screen (S2210), and ends the process.
The logout screen created by the search space setting unit 12, that is, the WEB page of the logout screen is transmitted to the WEB page display unit 21 by the WEB page transmission unit 11 and displayed on the display device 27.

FIG. 23 shows an example of the configuration of a search system according to the second embodiment of the present invention.
The search system according to the second embodiment includes a search space setting server 1, a search server 3, a plurality of file servers 4, and a plurality of clients 2.
The search space setting server 1, the search server 3, the plurality of file servers 4, and the plurality of clients 2 (hereinafter referred to as “servers”) are connected to each other via a wired or wireless communication line such as a LAN 9. Has been.
Since the configuration of each server and the like in the second embodiment is the same as that in the first embodiment, the description in FIG. 23 is omitted. The functions and operations of each server and the like are the same as those in the first embodiment.
The second embodiment is different from the first embodiment in that a part of the file server 4 exists on a different LAN segment from the search space setting server 1.
As described above, the search space setting server 1, the search server 3, the file server 4, and the client 2 can be connected by communication lines having various configurations.

FIG. 24 shows an example of the configuration of a search system according to the third embodiment of the present invention.
The search system according to the third embodiment includes a search space setting server 1, a search server 3a, a search server 3b, a plurality of file servers 4, and a plurality of clients 2.
The search space setting server 1, the search server 3a, the search server 3b, the plurality of file servers 4, and the plurality of clients 2 (hereinafter referred to as “servers”) are wired or wireless such as the LAN 9 and the Internet 9a. The communication lines are communicably connected to each other.
Since the configuration of each server and the like in the third embodiment is the same as that in the first embodiment, the description in FIG. 24 is omitted. The functions and operations of each server and the like are the same as those in the first embodiment except for the points described later.

The third embodiment is that a part of the search server 3 and the file server 4 exist on a different LAN segment from the search space setting server 1, and each LAN segment is connected to be communicable with each other by the Internet 9a. Different from one embodiment.
In the third embodiment, the process when the search space setting unit 12 searches the search space (S1810 in FIG. 18) is different from the first embodiment. That is, also in the third embodiment, from the search management record 130 (target search management record 130) for the client 2 of the WEB page display unit 21 that transmitted the search processing request, similarly to the first embodiment, the search space ID 132 (target The search space ID 132) is acquired, and a search command is created based on the search target 176 of the search space definition record 170 in which the target search space ID 132 matches the search space ID 171 and the search keyword received from the WEB page display unit 21. However, after that, in the third embodiment, a search command is transmitted to a plurality of search units 31.
At this time, if each search unit 31 can understand the same search command, for example, the search program for realizing each search unit 31 is the same, the search command transmitted to each search unit 31 may be the same. By doing in this way, the function of the search space setting part 12 can be made simpler.

On the other hand, if each search unit 31 cannot understand the same search command due to different search programs for realizing each search unit 31, it is necessary to transmit a different search command to each search unit 31. In this case, although not shown in FIG. 24, for example, search command creation rules for each search unit 31 are stored in the storage device 16 of the search space setting server 1, and the search space setting unit 12 stores the search command. A search command may be created by referring to the creation rule.
For example, “(Keyword = 'projectX'and (Filetype =' doc '
or 'txt') "is set, and the search unit 31a of the search server 3a has both a search keyword and a search function based on a file extension. However, the search unit 31b of the search server 3b In this case, the search space setting unit 12 uses “SearchFile (Keyword = 'projectX'and (Filetype) as a search command for the search unit 31a. = 'doc' or 'txt')) ”(search for files that contain the keyword 'projectX' and have a file extension of 'doc' or 'txt'). 12 creates "SearchFile (Keyword = 'projectX')" (searches for a file including the keyword 'projectX') as a search command for the search unit 31b, and the search result data received from the search unit 31b. Of file extension may be selected file is 'doc' or 'txt'.

  Searches by the search units 31 can also be performed in parallel. Here, “parallel” means that a search command is transmitted to one search unit 31, waits until reception of search result data from the search unit 31, and a search command is sent to another search unit 31 after reception. Instead of transmitting, for example, by creating a thread corresponding to each of the plurality of search units 31, a search command is transmitted to each search unit 31 and search result data is received from each search unit 31. This means that the search by the unit 31 is performed independently.

Furthermore, even if the search of a certain search unit 31 fails due to a communication line abnormality or the like, when the search of the search space as a whole (S1810) succeeds, as in the case where the search of other search units 31 succeeds, The search space search result 135 may be set (S1830). By doing in this way, unless the search of all the search parts 31 fails, the operator of the client 2 can see the search result data about search space.
On the other hand, if any one of the searches of the search unit 31 fails, the search space setting unit 12 may create an error screen and end the process. In this way, the operator of the client 2 can determine that all search processes have been performed normally when the search screen is displayed.

  As described above, by using the search system according to each embodiment described above, not only one or a plurality of computers in the organization, but also each computer on the Internet can be used to search for a really necessary file suitable for the search purpose. Is possible.

  Incidentally, in the first to third embodiments described above, for example, as shown in FIG. 15, the content displayed as a report is the same as the content when the report is created. For example, the search system has a function of changing the contents of the search result 184 of the report record 180, so that a new search result can be added to the report after the report is created, or the search result included in the report can be changed. It is also possible to edit. However, even in this case, the content displayed as the report is the same as the content when the report (for example, the content of the search result 184) is changed.

On the other hand, it is convenient for an operator who has displayed the report contents to know that, for example, when the report is displayed, a part of the displayed search result has already been deleted and does not exist. As described above, there is a need to display not only the contents of a report when a report is created or changed, but also a more dynamic display.
Such needs are not unique to search systems, but are generally inherent in systems that display WEB pages. Therefore, conventionally, dynamic content display technologies such as CGI and SSI (Server Side Include) are known.
Particularly in recent years, SNS (Social Networking Service) has been actively used, and a standard API (for example, OpenSocial) is provided so that each user in the SNS can easily display dynamic content on a WEB page. Is also provided.

The search system according to each of the above-described embodiments can also perform report display in accordance with user needs by performing dynamic display using such a technique.
Hereinafter, an example of performing dynamic display on a report will be described. Specifically, an example of storing search conditions at the time of creating a report and performing a re-search while displaying a report or displaying a history of a re-search (hereinafter referred to as “an example of enabling re-search”). ).

FIG. 25 shows an example of the data structure of the report file 18a according to an example that enables re-searching.
The report file 18a for enabling re-searching is composed of one or more report records 180a, similar to the report file 18 of the first to third embodiments shown in FIG. 5, and includes a report ID 181 and a report name. Data items of 182, search space ID 183, and search result 184 are stored. In addition, in the report record 180a for enabling the re-search, the respective data items of the search condition 185 and the re-search result 186 are stored.
The search result 184 can be displayed as it is as a part of the WEB page, so that the search space setting unit 12 receives the content of the file itself as the search result data from the search unit 31, the file name, The URL of the file is edited in the HTML format. For this reason, FIG. 25 does not repeat the n times as shown in FIG.

In the search condition 185, the search condition when the report record 180a is created is set. That is, when the WEB page display unit 21 transmits a report creation processing request to the WEB page transmission unit 11, the WEB page display unit 21 is displayed together with the report name and the URL displayed on the selection result display unit (G132 in FIG. 13). The search condition (search condition specified by the operator of the client 2 like the keyword input in the keyword input field in FIG. 10 in the first embodiment) in the WEB page transmission unit 11 Send. When creating the report record 180a (S2010 in FIG. 20), the search setting unit 12 sets the received search condition (the keyword input in the keyword input field in FIG. 10 in the first embodiment) as the search condition 185. .
Nothing is set in the re-search result 186 when the report record 180a is created. When the re-search described later is performed, the re-search result (the content of the file itself that matches the re-search condition, its file name, The URL of the file is set.

Each time the re-search is repeated, the re-search results are accumulated. For example, when m re-searches are performed, m re-search results 186 are set. In each of the m re-search results 186, one or more combinations of the contents of the file itself, the file name, the URL of the file, etc. that match the re-search conditions are set, or match the re-search conditions. A message indicating that there is no file to be set is set.
The search condition 185 and the re-search result 186 are not necessarily set in the report record 180a, and can be set in a file different from the report file 18a.

  Hereinafter, an example that enables re-search will be described focusing on operations different from the first to third embodiments with respect to the operation of the search system, while showing the screen displayed on the display device 27 of the client 2.

FIG. 26 shows an example of a report creation screen according to an example that enables re-search.
The selection result display unit (G132) on the report creation screen not only displays the selection result, but also allows the user to enter characters or change the display content in any part of the selection result display unit (G132). Then, the operator of the client 2 operates the input device 26 and inputs a character string for instructing that to a part where the re-search result or the like is to be displayed. In the example of FIG. 26, “<vsscontrol></vsscontrol>” is input at the top of the selection result display section (G132). Note that the character string (hereinafter referred to as “control designation”) for instructing to display the re-search result or the like is “<vsscontrol></vsscontrol>” in an XML (Extensible Markup Language) style in this example. However, any character string or the like may be used as long as it can be identified that it is a part for which a re-search result or the like is to be displayed.

When the operator of the client 2 clicks the create button on the report creation screen, the WEB page display unit 21 displays the report name input in the report name input field (G131), the HTML corresponding to the selection result display unit (G132), and The search condition is transmitted to the WEB page transmission unit 11 together with the report creation processing request.
The WEB page transmission unit 11 activates the search space setting unit 12 when receiving a report creation processing request or the like from the WEB page display unit 21. When creating the report record 180a (S2010 in FIG. 20), the search space setting unit 12 edits and searches the HTML corresponding to the received selection result display unit (G132) as necessary, as described below. The search condition set to the result 184 and the search condition received from the WEB page display unit 21 is set to the search condition 185.

Here, editing of HTML (hereinafter simply referred to as “selection result display unit”) corresponding to the selection result display unit (G132) will be described.
The search space setting unit 12 analyzes whether or not the control result is included in the selection result display unit, and if the control specification is not included, the selection result display unit is not edited. On the other hand, when the control designation is included in the selection result display portion, the control designation portion is replaced with HTML for displaying a re-search button and a history display button, and a script executed when each button is clicked. . As will be described later, the selection result display section edited as described above is transmitted to the client 2, and a button or the like for executing a re-search process is displayed on the part of the selection result display section where the control designation has been input. Is done.

Next, the search space setting unit 12 does not create a search screen as in the first embodiment (S2020 in FIG. 20), but performs report content display processing instead. Specifically, the data set in the search result 184 of the created report record 180a is transmitted to the client 2 and the process is terminated.
Then, the WEB page display unit 21 refers to HTML or the like included in the transmitted data, and displays a display screen as shown in FIG.

FIG. 27 shows an example of a display screen (report display result) according to an example enabling re-search. Unlike the display screen (report display result) (FIG. 15) in the first to third embodiments, a display for re-search processing is made in the part where the operator of the client 2 inputs the control designation ( G152). The display unit (G152) for the re-search process has a re-search button and a history display button.
When the operator of the client 2 clicks the re-search button, the WEB page display unit 21 executes a script that records the operation when the re-search button is clicked, and issues a re-search request together with the report ID of the displayed report. It is transmitted to the page transmission unit 11 (the report ID of the displayed report may be set in a script in which an operation when the re-search button is clicked, for example).

When receiving the re-search request, the WEB page transmission unit 11 activates the search space setting unit 12. The search space setting unit 12 acquires the report record 180a of the received report ID, and searches (re-searches) the search space based on the search condition 185. A specific search method is as described for step S1810 in FIG. The search space setting unit 12 sets the re-search result to the re-search result 186. If there is no file that matches the re-search condition, a message indicating that is set in the re-search result 186.
Next, the WEB page transmission unit 11 transmits the re-search result to the WEB page display unit 21, and the WEB page display unit 21 displays the received re-search result on the display unit (G152) for the re-search process.

FIG. 28 shows an example of a display screen (re-search execution result) according to an example that enables re-search. In the illustrated example, the file names and URLs of three files that match the re-search condition are displayed.
The re-search process can be performed any number of times. Each time a re-search is performed, a re-search result 186 of the corresponding report record 180a is added.
On the other hand, when the operator of the client 2 clicks the history display button, the WEB page display unit 21 executes a script that records the operation when the history display button is clicked, and requests a history display together with the report ID of the displayed report. Is transmitted to the WEB page transmission unit 11 (the report ID of the displayed report may be set in a script in which an operation when the history display button is clicked, for example).
When receiving the history display request, the WEB page transmission unit 11 activates the search space setting unit 12. The search space setting unit 12 acquires the report record 180a of the received report ID, edits the re-search history from the setting contents of the re-search result 186 (1 to m), and transmits it to the WEB page display unit 21.
The WEB page display unit 21 displays the received re-search history on the display unit (G152) for the re-search process.

FIG. 29 shows an example of a display screen (re-search history selection result) according to an example enabling re-search.
In the illustrated example, the re-search has already been performed three times. The date of each re-search (for example, “2010.02.01”), the user ID of the operator who performed the re-search (for example, “usr2”), and the re-search The number of files that match the search criteria (for example, “3”) is displayed. When the re-search result 186 is set, such a history display can be performed by setting the date of the re-search and the user ID of the operator.

In the above, the method of inputting the control specification at the time of report creation to enable re-search and history display was explained. However, the operator of the client 2 tries to perform the re-search and history display rather than after the report is created. , More likely after the passage of time.
Therefore, not only when the report is created, but when the operator of the client 2 displays the setting content of the report record 180a on the display device 27 (for example, when a report content display processing request is made, a report that matches the search condition as shown in FIG. 15). It is preferable to display the display unit (G152) for the re-search process even when the message is displayed. At that time, control designation input may be enabled.

As described above, the display unit (G152) for the re-search process is displayed at various timings for displaying the setting contents of the report record 180a, not only at the time of creating the report, and by further enabling control designation, The following effects can be obtained.
First, it is possible to easily perform a re-search using the same keyword or the like that has created the report record 180a in the past. Further, by comparing the re-search result and the search result set in the report record 180a on the same screen, it is possible to know the presence of a newly searched file or a file that no longer matches the search condition.
Also, an operator different from the operator who created the report record 180a can perform a re-search with the same search conditions as the operator who created the report record 180a without being aware of the search conditions such as keywords. When the operator who created the report record 180a and the operator who performs the search again have different file access authority, it is possible to newly find a file that matches the search condition.

  In addition, the operator who performs the re-search can know from the history display that there is a file that does not have access authority but matches the search condition. For example, in the example of the history display in FIG. 29, four searches were made on November 1, 2009, and five searches were made on February 1, 2010, three months later by re-searching by the operator with the user ID “usr1”. The conditions are met. On the other hand, only 3 items satisfy the search condition by the re-search on February 1, 2010 by the operator with the user ID “usr2”. With this history display, the operator with the user ID “usr2” can guess that there is a file that cannot be searched because he / she does not have access authority. It is also possible to get the contents of the file to be taught within a range where there is no.

By the way, in the above description, the display unit (G152) for the re-search process and the method of combining the conventional techniques such as CGI to enable the execution of the re-search have been described. As described above, OpenSocial It is also possible to use relatively new technologies such as
As described above, not only when the report record 180a is created, but also when the report record 180a that matches the search condition is displayed (for example, when the display as shown in FIG. 15 is performed), the control relating to the search condition is performed. A designation may be entered. Referring to FIG. 15 as an example, the report content display section (G151) may be editable so that control designation can be input at an arbitrary location in the report content display section (G151). Then, although not shown in FIG. 15, when the “Update” button is clicked, the input control designation is changed and displayed on the display unit for the re-search process as in the case of creating the report record 180a. do it. In this case, the search condition for searching the report record 180a may be set in the search condition 185 of the report record 180a.

  Furthermore, when the control designation can be freely input when the contents of the report record 180a are displayed as described above, the control designation may be input to a plurality of places without being limited to one place of the report. By doing in this way, the display part for the re-search process corresponding to various search conditions can be displayed on the arbitrary places of a report display, and an operator's convenience improves. In this case, it is necessary to set the search condition 185 and the re-search result 186 corresponding to each control designation.

  When the report content display section (G151) can be edited, not only the control designation can be input, but also the displayed report content can be changed. Similarly to the case of creating a report, a file search result (for example, search result data displayed in the search result display part (G103) of the search screen in FIG. 11) may be added to the report. In this case, the search condition at the time of report creation and the search condition related to the file search result added to the report (hereinafter referred to as “past search condition”) are set in the report record 180a. When a display for re-search processing is first displayed after inputting the control designation, a list of past search conditions can be displayed, and the re-search condition can be selected from the list. By doing so, the degree of freedom of control designation is further increased, and the convenience for the operator is improved.

FIG. 30 shows a display screen (report display) according to an example that enables re-search when a list of past search conditions is displayed when the display unit for re-search processing is first displayed as described above. An example of (result) is shown.
In FIG. 30, two rows are displayed on the display unit (G152) for the re-search process as a list of past search conditions. The bottom row shows that the operator with user ID "usr1" specified a keyword "Product X" on November 1, 2009, and set at least part of the search results in the report. . The upper row shows that on January 10, 2010, the operator with user ID “usr2” specified two keywords, “Product X” and “Development System”, and searched for at least part of the search results. Indicates that it has been added to the report.
When the operator of the client 2 clicks a radio button corresponding to one of the search conditions (in the example of FIG. 30, the radio button displayed in the lower row is clicked), and the update button is clicked, Specifies which search condition the control specification is for.

  By the way, in the above description, the control designation related to the re-search process has been described. However, in addition to this, various operations such as a dynamic display for displaying the storage capacity of the report record 180a that matches a predetermined condition, for example. Display may be possible. In this case, the dynamic display on the report display indicates what kind of dynamic display you want to display, for example "<vsscontrol id = 001> </ vsscontrol>" A character string (hereinafter referred to as “control designation” in this sense) with an ID (“001” in this example) can be input, and the search space setting unit 12 edits the search result 184 based on the ID of the character string. You can change it.

Further, when the search space setting unit 12 edits the search result 184, the control designation is input while leaving a trace of the control designation being input by commenting out instead of replacing the control designation with the display content or the like. A predetermined HTML, script, or the like may be set at the location. By setting in this way, it is possible to delete or change the control designation once input.
Then, by combining the various technologies described above, it is possible to perform convenient report display including dynamic content.

As described above, according to the present invention, it is possible to reduce the ratio of unnecessary digital information included in search results under a condition where there are a large number of digital information to be searched.
In the present invention, at least one virtual search space including a search target having a high possibility that a file (digital information) suitable for a search purpose or the like exists in advance is set. Then, the user logs in to a search space in which there is a high possibility that a necessary file or the like exists in accordance with the search purpose and searches in the search space. The user further selects a file or the like that matches the purpose of the search space and stores it in a report file in association with the search space. When a user requests a search for a desired file or the like, if a report file exists, both the search space and the report file are searched. Each search result is displayed on a separate screen.
The user can obtain a search result with low noise including a file taken in by another user from the report file. On the other hand, the user can newly search for a file or the like that has a high noise level but is not yet captured in the report file from a search space in which a necessary file or the like is likely to exist.

  Although the embodiments of the present invention have been described above, various modifications and combinations necessary for design reasons and other factors are described in the inventions described in the claims and the specific embodiments described in the embodiments of the invention. It is included in the scope of the invention corresponding to the example.
