Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a file search device for searching for a file indicated by a search key, and a computer-readable recording medium for recording a list of file names used in the device. A file search device that enables a keyword to be assigned or a file storage location to be changed without imposing a heavy load, and a computer in which a list of file names used in the device is recorded And a readable recording medium.

[0002] In a filing system in which files are stored on a server and managed centrally, a keyword is assigned to a registered file in addition to the file name, and a character string serving as a search key is obtained. Given a file, search for the file that the user needs by searching for the file name that has that string, or search for the file that the user needs by searching for the keyword that has that string. Provides functions.

In the filing system, the storage location of a file is changed, or the keyword assigned to the file is changed. From now on, to realize this function, it is necessary to build a technology that can easily deal with such changes.

[0004]

2. Description of the Related Art In a conventional filing system, a file list for managing a correspondence between a file name and a storage location (such as a full path) of the file and a file are allocated to the file in order to realize a file search process using a search key. In this configuration, two search tables are prepared, that is, a keyword table that manages a correspondence between a keyword to be stored and a storage location (such as a full path) of the file.

When a file is searched from a file name, a character string serving as a search key is given. By searching the file list, a file name having the character string is searched. It was processing to search for a file by getting the file storage location to point to.

When a file name is searched from a keyword, a character string serving as a search key is given.
By searching the keyword table, a keyword having the character string is searched, and a file storage location indicated by the keyword is obtained to search for a file.

[0007]

However, according to such a conventional technique, when a keyword is changed, a large load is imposed on the filing system, and when the storage location of the file is changed, the filing system is changed. There is a problem in that a large load is imposed on the device.

That is, when changing the keyword of a certain file, it is necessary to scan the keyword table having the above-described table structure to change a necessary portion, and also to change the storage location of the file. ,
This keyword table must be scanned to rewrite the storage location information of the corresponding file, which causes a problem that a heavy load is imposed on the filing system.

In the case of a filing system having this keyword table as a part of the basic structure of the system, the load may not be a problem, but it is necessary to use Windows (registered trademark of Microsoft Corporation, USA). In a filing system based on a hierarchical structure of folders and files, this load becomes a serious problem.

[0010] The present invention has been made in view of the above circumstances, and there is a case where a configuration for retrieving a file indicated by a retrieval key is adopted, in which a keyword assigned to a file is changed or a storage location of a file is changed. If you do
It is an object of the present invention to provide a new file search device capable of realizing it without applying a large load, and to provide a new computer-readable recording medium in which a list of file names used in the device is recorded. .

[0011]

In order to achieve this object, a file search apparatus according to the present invention uses a file defined by incorporating one or more keywords assigned to the file into a file name presented by a user. Means for managing the correspondence between the name and the storage location of the file presented by the user; and, when the file name is specified as a search target, by searching for the file name presented by the user managed by the management means. , Search the file indicated by the search key, and if the keyword is specified as a search target,
A search means for searching for a file indicated by a search key by searching for a keyword with a built-in file name managed by the management means.

[0012] When adopting this configuration, the management means uses a file name defined by incorporating an index in place of the keyword for a file name that exceeds the specified length by incorporating the keyword. A second management unit configured to manage a correspondence relationship and manage a correspondence relationship between the index and one or more keywords assigned to the index, wherein the search unit specifies the keyword as a search target In such a case, when the file name incorporates an index, the keyword managed by the second management means indicated by the index is searched to search for the file indicated by the search key.

Here, the list of correspondences managed by the management means and the list of correspondences managed by the second management means can be recorded on a computer-readable recording medium.

In the present invention, the file name of the file to be registered in the filing system is defined as "file name portion (file name presented to the user)" having an original meaning and "keyword portion (a plurality of keywords) having a meaning as a keyword. Is defined as a character string whose use is prohibited in the file name portion and the keyword portion, and has a meaning as a boundary between the two. ".

Using the file name configured as above,
When a file name is requested to be displayed by a request from a client-side Web browser or the like, the filing system displays only the original meaning of the "file name part" and does not display the part after the "separator character part". .

In addition, the filing system, when changing a keyword assigned to a file in response to a request from a client-side Web browser or the like,
Change the "keyword part" of the file name. this is,
It can be executed with no heavy load, just a simple change of the file name.

Further, when the filing system moves a file to another location in response to a request from a client-side Web browser or the like, a simple list of the full path notation of the file (correspondence managed by the management means)
And simply move the file itself, so it can be executed without imposing a heavy load.

Further, in the filing system, when a registered file is searched by a keyword in response to a request from a Web browser or the like on the client side, there is no difference from performing a search on the file name as it is. That is, it is possible to know the storage location of the file to which the keyword having the search key is assigned simply by scanning the simple list of the full path notation of all the registered files (correspondence managed by the management means).

On the other hand, there is generally an upper limit on the length of the file name on the OS that operates the filing system. From now on, if the “keyword portion” becomes longer, this upper limit will be exceeded.

To cope with such a case, a reference index number is described in the "keyword" portion of the file name, and a keyword table for managing the correspondence between the reference index number and the keyword assigned thereto is prepared. Take the configuration.

As described above, according to the present invention, even when a keyword assigned to a file registered in the filing system is changed, it can be executed without imposing a large load on the filing system. Also, when a file is moved to another location, it can be executed without imposing a large load on the filing system. Then, even when searching for a keyword, it can be executed without imposing a large load on the filing system.

Therefore, the load on the filing system can be reduced and its performance can be improved.

Further, the present invention can cope with a file name longer than the length permitted by the OS, and there is no restriction on the length and number of keywords assigned to the file.

[0024]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail according to an embodiment applied to a server / client system.

FIG. 1 shows an embodiment of a server 1 equipped with the present invention.

The server 1 according to this embodiment adopts a configuration for managing a file and posts the contents of the file to a plurality of clients 2 (deploying the browser 200) connected via the network 3. It performs processing and includes a file management mechanism 10, an HTML file editing program 20, a file search program 30, and a keyword registration change program 40.

The file management mechanism 10 has a configuration in which a plurality of folders 11-i (i = 1 to n) are prepared and files 12 to be posted to the client 2 are stored therein. Further, an HTML file 13 describing screen data to be displayed on the display of the client 2
And a file list 14 for managing the correspondence between the file name and the full path to the folder 11-i that stores the file 12 of the file name.

Here, the HTML file 13 is stored in one of the folders 11-i. Here, for the sake of convenience, the folder 11- in which the file 12 to be posted to the client 2 is stored. It is shown so as to be provided independently of i.

The HTML file editing program 20
It is installed via a floppy disk, a line, or the like and operates on the memory to execute the editing process of the HTML file 13.

The file search program 30 is installed via a floppy disk or a line, operates on a memory, and interacts with the client 2 to execute a search process for the file 12 requested by the client 2.

The keyword registration change program 40 is installed via a floppy disk, a line, or the like, operates on a memory, and interacts with the client 2 to execute a registration change process of a keyword assigned to the file 12.

FIG. 2 shows an embodiment of the list data of the file list 14. Here, this list data is recorded on a computer-readable recording medium.

The file list 14 manages the correspondence between the file name and the full path to the folder 11-i that stores the file 12 having the file name, using the folder 11-i as a management unit. The invention is characterized in that a keyword is incorporated in the file name.

In the present invention, for example, as shown in the third list data of FIG. 2, the original file name to be posted on the client 2 called “update history” includes “competitor investigation” and “persis "Update History $! D Competition Survey $! Perisis Sales.htm, 1999/10 incorporating the keyword" sales "(underlined in the figure)
/ 19 09: 59,1 "$! D: Delimiter between file name and keyword $ !: Delimiter between keyword and keyword htm: Extension (symbol indicating file attribute) : 59: File registration date and time 1: File size (K) A file name on the OS is used.

Then, the full path to the folder 11-i that stores the file 12 with the file name “update history” is “G: \ Filer2 \ 2. Keyword demo \ 1. Name embedding” Name embedding: The folder 11 -i folder name, the file list 14 is a file name including this keyword, as shown in the third list data in FIG. ! Perisis Sales.htm, 1999/10
/ 19 09: 59,1 "and the corresponding relationship between" G: \ Filer2 \ 2. Keyword demo \ 1. Name embedding "which is the full path to the folder 11-i that stores the file 12 with that file name I am trying to do it.

FIG. 3 shows an embodiment of a processing flow executed by the HTML file editing program 20, and FIG. 4 shows an embodiment of a processing flow executed by the file search program 30. Next, according to this processing flow, the operation processing of the embodiment configured as described above will be described.

As one of the HTML files 13, FIG.
Is displayed on the display of the client 2. This HTML file 13 is
The folder 11-i is prepared in association with the folder 11-i.
When a file name list display request is issued by designating -i, the file name list stored in the folder 11-i is displayed.

The HTML file editing program 20
When a new file 12 is additionally registered in the folder 11-i by a file registration program (not shown), the processing flow of FIG. 3 is executed to edit the HTML file 13 which controls the display processing of the screen shown in FIG. Execute the processing to be performed.

That is, when a new file 12 is additionally registered in the folder 11-i, the HTML file editing program 20 firstly executes a file registration (not shown) in step 1 as shown in the processing flow of FIG. The file name of the file 14 passed from the program is obtained. This file name is, as described above, the file 14
It is composed of keywords that are assigned to.

Subsequently, in step 2, an HTML file (for displaying the screen shown in FIG. 5) for displaying a file name list prepared in association with the folder 11-i to which the file 12 has been added is stored. Load from location.

Subsequently, in step 3, the keyword portion is removed from the file name obtained in step 1.

For example, in step 1, "Update history $! D competitor investigation $! Perisis sales.htm, 1999/10
/ 19 09: 59,1 "
・ By removing the keyword "Perisis Sales", the original file name "Update History", the file extension "htm", and the file registration date and time "1999/1"
0/19 09:59 ”and the file size“ 1 ”.

Subsequently, in step 4, a file name excluding the keyword portion is added to the HTML file 13 read in step 2 as a file name to be displayed and stored in the original storage location.

As described above, the HTML file editing program 20 stores the new file 12 in the folder 11-i.
Is added to the file 12, the keyword portion is removed from the file name of the file 12 in which the keyword is incorporated, and an HTML file 13 in which other data is used as display data is created.

As a result, as shown in FIG. 5, the client 2 lists the file names composed only of the original file name parts (the file name list of the files 12 stored in the designated folder 11-i). Can be seen.

When the “key button (button prepared in association with the file name)” displayed in FIG. 5 is operated, the keyword registration change program 40 is displayed on the display of the client 2 as shown in FIG. Display such a keyword registration change screen, and use it to display client 2
By interacting with, the keyword registration change process is performed, and in response to the keyword registration change, the process of registering and changing the keyword-incorporated file name stored in the file list 14 is performed.

Here, FIG. 6 assumes that a keyword “DPS9600pro” is newly added to the file name “Pragma001”.

On the other hand, when the “search button” displayed in FIG. 5 is operated, the file search program 30
By executing the processing flow of (1), the file 12 required by the client 2 is searched, and the list of the search results is displayed.

That is, the file search program 30
When the "search button" displayed in FIG. 5 is operated, as shown in the processing flow of FIG. 4, first, in step 1, the search screen shown in FIG. Then, by interacting with the client 2, the character string of the search key and the search condition are input.

Here, in the search screen shown in FIG.
One search key can be entered, and only the original file name portion (title) can be set as a search target, or the original file name portion and the keyword portion incorporated in the file name can be set as search targets. . Furthermore,
File types (file extensions) can be set as search targets.

Subsequently, in step 2, it is determined whether or not the keyword is also set as a search target, and when it is determined that the keyword is not set as a search target, that is, only the original file name is searched. When it is determined that the search condition has been set, the process proceeds to step 3 to scan the file list 14 to search for the file 12 having the file name portion that matches the search key (when the AND condition or the OR condition is set). , And a search that satisfies the search is performed), and the search result is displayed on the display of the client 2 in step 4.

On the other hand, when it is determined in step 2 that the keyword is also set as the search target, that is, it is determined that the keyword assigned to the file 12 is set as the search target in addition to the original file name. Sometimes, the process proceeds to step 5 and the file list 14
To search for a file 12 having a file name portion / keyword portion that matches the search key (AN
When the D condition or the OR condition is set, a search for a condition that satisfies the condition is performed), and in a subsequent step 6, the search result is displayed on the display of the client 2.

As described above, when the search key is designated by the client 2, the file search program 30
When only the original file name is set as a search target, the original file name portion managed in the file list 14 is set as a search target, and a file 12 having a file name portion that matches the search key is searched. The result is displayed on the display of the client 2, and when a keyword is set as a search target in addition to the original file name, the original file name part managed in the file list 14 and the keyword part incorporated in the file name are displayed. Is searched, a file 12 having a file name portion / keyword portion that matches the search key is searched, and the result is displayed on the client 2 display.

According to the processing of the file search program 30, for example, when "scanner" is designated as a search key, "scanner" is provided on the display of the client 2 as the original file name as shown in FIG. List of file names of file 12 and "scanner"
And a list of file names of the files 12 having the keyword as a keyword portion.

As described above, in the prior art, FIG.
As shown in (b), the file 12 indicated by the search key is searched using a file list for managing the correspondence between the full path and the file name and a keyword table for managing the correspondence between the full path and the keyword. On the other hand, in the present invention, as shown in FIG. 9A, the keyword is incorporated in the file name.
Using a file list 14 that manages the correspondence between the file name embedded with the keyword and the full path to the folder 11-i that stores the file 12 with that file name,
The configuration is such that the file 12 indicated by the search key is searched.

In the present invention, a configuration is adopted in which a keyword is incorporated into a file name. However, according to this configuration, the file name may exceed the length permitted by the OS. In such a case, as shown in FIG.
0 is provided with a keyword table 15 having a table structure different from the keyword table provided in the conventional technology.

FIG. 11 shows an embodiment of the table data of the keyword table 15. Here, this table data is recorded on a computer-readable recording medium.

As shown in this figure, in the keyword table 15 provided in the present invention, for example, the index “3” indicates that “PD-MP5HMN” and “paper thickness automatic adjustment”
And manages the correspondence between the index and the keyword assigned to the index, such that the keywords "paper automatic loading function" and "paper passage opening / closing structure" are assigned.

In response to the keyword table 15, in the file list 14 according to this embodiment, as shown in FIG. 12, the file name incorporating the index and the folder 11-i storing the file 12 of the file name are stored. A configuration for managing the correspondence with the full path is adopted.

For example, in the case of the second list data shown in FIG. 12, the original file name to be posted on the client 2 "multipurpose printer series" has an index "3" (underlined in the figure). "Multipurpose printer series $! R3.htm <mof>, 1999/06/21 1
0: 00,1566 "$ !: Delimiter between file name and index htm <mof>: Extension (symbol indicating file attribute) 1999/06/21 10:00: File registration date and time 1566: File It manages the correspondence between the file name "size" and "G: \ Filer2 \ 2. Keyword Demo \ 2. See Table" which is the full path to the folder 11-i that stores the file 12 with that file name. Here, “table reference” described at the end of the full path is a folder name.

According to this management configuration, the original file name “multipurpose printer series” is added to “PD-MP5
The keywords "HMN", "paper thickness automatic adjustment", "paper automatic loading function", and "paper passage opening / closing structure" are assigned.

Even when the file name with the index is used, when displaying the file name on the display of the client 2, the original file name portion without the index is removed according to the description of the HTML file 13 as shown in FIG. Will be displayed.

FIG. 14 shows an embodiment of a processing flow executed by the keyword registration change program 40 to realize this embodiment. FIG. 15 shows a processing executed by the file search program 30 to realize this embodiment. 1 illustrates an embodiment of a flow. Next, operation processing of this embodiment will be described according to this processing flow.

When the “key button (button prepared in association with the file name)” displayed in FIG. 13 is operated, first, as shown in the processing flow of FIG. First, in step 1, by referring to the file list 14, the keyword assigned to the file 12 indicated by the key button is acquired, and a keyword registration change screen as shown in FIG. To be displayed.

At this time, when an index is incorporated in the file name, the keyword assigned to the file 12 indicated by the key button is obtained by specifying the keyword indicated by the index from the keyword table 15. Become.

Subsequently, in step 2, a new keyword is input by inputting a keyword to be input on the keyword registration change screen.

Subsequently, in step 3, a file name (= [full path] + [file name portion] + [separator] + [delimiter] + [keyword] + [separator] + [Keyword part] +
It is determined whether or not the number of characters (..) falls within the upper limit allowed by the OS.

When it is determined by this determination process that the number falls within the upper limit allowed by the OS, the process proceeds to step 4 to generate a file name in which a keyword is directly incorporated, and the correspondence between the file name and the full path is determined. Is registered in the file list 14, and the process is terminated.

That is, the file name registered in the file list 14 (= [file name portion] + [delimiter]
+ [Keyword part] + [separator] + [keyword part] +...), And as shown in FIG. 2, the correspondence between the file name and the full path is registered in the file list 14. That's how it works.

On the other hand, if it is determined in step 3 that the number does not fall within the upper limit allowed by the OS, the flow advances to step 5 to determine whether or not the file name of the file 12 indicated by the key button is an index-incorporated one. Judge,
If it is determined that the file is a file having a built-in index, that is, if it is determined that the file name is in a format that refers to the keyword table 15, the process proceeds to step 6 to acquire the used index.

Subsequently, in step 7, the keyword managed by the keyword table 15 indicated by the obtained index is changed to the newly input keyword, and the process is terminated.

On the other hand, if it is determined in step 5 that the file name of the file 12 indicated by the key button is not the one with the built-in index, the process proceeds to step 8 and
A new index not used in the keyword table 15 is acquired. Subsequently, in step 9, a file name in which the index is incorporated is generated, the correspondence between the file name and the full path is registered in the file list 14, and the process ends.

That is, the file name registered in the file list 14 (= [file name portion] + [delimiter]
+ [Index symbol]), and the correspondence between the file name and the full path is registered in the file list 14 as shown in FIG.

Subsequently, in step 10, the pair data of the index obtained in step 8 and the newly input keyword is registered in the keyword table 15, and the processing is terminated.

As described above, when the keyword registration change program 40 follows the embodiment of FIG. 10, the keyword registration change screen as shown in FIG. The client 2 interacts with the client 2 to perform a keyword registration change process, and in response to the keyword registration change, changes a file name with a keyword stored in the file list 14 or stores the keyword in the keyword table 15. You can change the keywords to be used,
For example, processing such as addition of new table data to the file No. 5 is performed.

On the other hand, when the “search button” displayed in FIG. 13 is operated, first, as shown in the processing flow of FIG. By displaying the search screen on the display of the client 2 and interacting with the client 2,
Enter the search key character string and search conditions.

Subsequently, in step 2, it is determined whether or not the keyword is also set as a search target, and when it is determined that the keyword is not set as a search target, that is, only the original file name is searched. When it is determined that the search condition has been set, the process proceeds to step 3 to scan the file list 14 to search for the file 12 having the file name portion that matches the search key (when the AND condition or the OR condition is set). , And a search that satisfies it) is performed, and in a succeeding step 4, the search result is displayed on the display of the client 2.

On the other hand, when it is determined in step 2 that the keyword is also set as the search target, that is, when it is determined that the keyword is set as the search target in addition to the original file name, the process proceeds to step 5. By scanning the keyword table 15, a keyword matching the search key (when an AND condition or an OR condition is set, a search that satisfies the keyword is searched).
Identify the index with.

Subsequently, in step 6, the file list 1
4 is scanned to search for a file 12 having a file name portion that matches the search key (when an AND or OR condition is set, search for one that satisfies it) and identified in step 5 A file 12 having an index portion that matches the index is searched, and in a subsequent step 7, the search result is stored in the client 2.
On the display.

As described above, when the search key is designated by the client 2 in the embodiment of FIG. 10, the file search program 30 executes the file search when only the original file name is set as the search target. With the original file name part managed in the list 14 as a search target, the file 12 having the file name part that matches the search key is searched, and the result is displayed on the display of the client 2, and the original file name is displayed. In addition, when a keyword is also set as a search target, an original file name part managed in the file list 14 and a keyword managed in the keyword table 15 are set as search targets, and a file name part matching the search key. The file 12 having the keyword is searched, and the result is displayed on the client 2 Than is processed as it continues to display as an example.

As described above, according to the present invention, the file name of a file to be registered in the filing system is defined as “file name portion” having an original meaning, “keyword portion” having a keyword meaning, and “file name portion”. And a "separator character part" defined as a character string whose use is prohibited in the keyword part and having a meaning as a boundary between the two.

Using the file name configured as above,
When a file name is requested to be displayed by a request from a client-side Web browser or the like, the filing system displays only the original meaning of the "file name part" and does not display the part after the "separator character part". .

The filing system, when changing a keyword assigned to a file in response to a request from a Web browser or the like on the client side,
Change the "keyword part" of the file name. this is,
It can be executed without a heavy load, just as a simple file name change.

When a file is moved to another location in response to a request from a Web browser or the like on the client side, the filing system rewrites the simple file list 14 with the full path notation of the file, and simply rewrites the file itself. Since it only needs to be moved, it can be executed without applying a large load.

Further, in the filing system, when a registered file is searched for by a keyword in response to a request from a Web browser or the like on the client side, there is no difference from performing a search for the file name as it is. That is, it is possible to know the storage location of the file to which the keyword having the designated search key is assigned by simply scanning the simple file list 14 of the full path notation of all the registered files.

On the other hand, there is generally an upper limit on the length of the file name on the OS that operates the filing system. From now on, if the “keyword portion” becomes longer, this upper limit will be exceeded.

Such a case can be dealt with by describing the reference index number in the “keyword” portion of the file name and preparing a keyword table for managing the correspondence between the reference index number and the keyword assigned thereto. Like that.

The present invention has been described with reference to the illustrated embodiments.
The present invention is not limited to this. For example, in the embodiment, a description has been given according to a specific example in which a search using a keyword is performed in combination with an original file name, but a search using only a keyword may be performed.

[0089]

As described above, according to the present invention,
Even when the keyword assigned to the file registered in the filing system is changed, it can be executed without imposing a large load on the filing system. Also, when a file is moved to another location, it can be executed without imposing a large load on the filing system. Then, even when searching for a keyword, it can be executed without imposing a large load on the filing system.

Therefore, the load on the filing system can be reduced and its performance can be improved.

Furthermore, it is possible to cope with a file name longer than the length allowed by the OS, and there is no restriction on the length and number of keywords assigned to the file.
