Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document retrieval apparatus for retrieving a relevant document based on an input keyword, and more particularly to displaying a title of a retrieved document.

[0002]

2. Description of the Related Art Conventionally, this type of document search apparatus searches for a corresponding document from a database based on a keyword input by a user, and then returns the number of responses (the number of documents searched) and the number of searched documents. Display the title list. After that, the document retrieval device retrieves the document having the title designated by the user from the database and displays it. By the way, the document search device first displays the number of answers and a list of titles as the search result, but the number of titles of the document displayed here matches the number of responses. However, when displaying a list of titles in the document search device, the number of displays is limited due to the capacity of the display memory, etc., so the list of titles cannot be displayed unless the number of responses is below a certain level. There is something. With such a document retrieval device, the user cannot see the title of the retrieved document or the content of the retrieved document unless the number of responses falls below a certain number. There is a problem that the number of answers must be set to a certain value or less by inputting a new keyword or the like to narrow down the number, otherwise the search work is interrupted.

On the other hand, since the document creating apparatus that has no limit on the number of titles that can be displayed displays all the titles of the retrieved documents even if the number of responses to the retrieved document is large, it takes time to display the titles. However, the display memory or the like must be equipped with a large capacity, and the cost of the device is increased accordingly. or,
In such a case, the user has to read all the displayed titles, which is a burden on the user. Also, there is a document search device that prioritizes the retrieved documents and displays the titles of the retrieved documents. However, in this case as well, the number of titles displayed tends to increase due to the prioritization. There is a drawback in that many users have to look at many titles, and the user's burden is increased similarly to the above.

[0004]

In the conventional document retrieval apparatus as described above, if the number of answers, which is the result of retrieving a document by inputting a keyword, is not narrowed down to a certain number or less, the title of the retrieved document or the retrieved document is retrieved. Document content is not displayed. For this reason, when the number of responses is large, the user has to enter a new keyword such that the number of responses is below a certain number to narrow down the number of search documents to below a certain number,
Otherwise, there was a drawback that the search operation would be interrupted here.

Therefore, the present invention eliminates the above-mentioned drawbacks and allows the user to arbitrarily set the maximum display limit number of titles so that a part or all of the titles of retrieved documents can be displayed without fail. The object is to provide a document retrieval device that is easy to use.

[0006]

According to the present invention, when a document in a storage device is searched on the basis of an input keyword, the number of answers and the title of the search document are displayed on the screen of the display device. Setting means for allowing the user to set the maximum display number of titles to be displayed, and if the number of responses is larger than the maximum number of display items set by the setting means, the titles are displayed on the screen of the display device up to the maximum display number. And an output means for performing the same.

[0007]

In the document retrieval apparatus of the present invention, the setting means causes the user to set the maximum number of displayed titles to be displayed. The output unit displays the title on the screen of the display device up to the maximum display number when the number of responses is larger than the maximum display number set by the setting unit. As a result, even if the number of responses exceeds the number of titles displayed, the titles are displayed up to the set number without narrowing down the number of responses, and the search operation can be advanced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a document search device of the present invention. Reference numeral 1 is a control device that includes a CPU 11 and a memory 12, and performs a document search process. Reference numeral 2 is a user inputting a keyword and a search operation instruction to the control device 1 with a keyboard or a mouse, or controlling the title display limit number. An input device 3 for inputting to the device 1 is a display device for displaying a keyword input from the input device 2, an instruction of a search operation, and the number of responses and titles of search documents, and 4 is a document to be searched. It is an external storage device.

FIG. 2 is a detailed view showing the function of the control device 1 described above. The CPU 11 of the control device 1 is the initialization unit 2
1, search processing unit 22, title display number setting unit 23, keyword input unit 24, search processing unit 25, response number output unit 2
6, each processing corresponding to the title output unit 27 and the display unit 28 is performed, and the title character string buffer 29 is stored in the memory 12.
Each of the title display number buffer 30 and the work buffer 31 is allocated.

The search setting unit 22 reads the data necessary for performing the search processing from the external storage device 4 and the setting information of the number of titles to be displayed, and sets the input device 2 and the display device 3 for inputting keywords and operating instructions. I do. The title display number setting unit 23 is activated by an instruction from the user's input device 2, sets the title display limit number for displaying the title of the answer document on the display device 3, and stores the set number in the title display number buffer 30. To do. The keyword input unit 24 receives a keyword for performing a search from the input device 2. The search processing unit 25 searches for the relevant document based on the input keyword, and obtains the number and title of the relevant documents. The number-of-responses output unit 26 outputs the number of responses of the relevant document obtained by the search processing unit 25 to the display device 3. The title output unit 27 outputs the title of the relevant document obtained by the search processing unit 25 to the display device 3 with the set number stored in the title display number buffer 30 as a limit.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. First, the initialization unit 21 of the control device 1 is activated in step 301 to start each buffer 29-
After initializing 31, the search processing unit 22 waits until the search setting unit 22 is activated. Next, the title display number setting unit 23
Is started in step 302, and a screen as shown in FIG. 4 is displayed on the display device 3 to allow the user to set the maximum display limit number of titles. When the user sees the screen as shown in FIG. 4, the user inputs the maximum number of titles to be displayed (MAXm) from the input device 2. The title display number setting unit 23 stores the input maximum title display number m, that is, 10 in the example of FIG. Here, the set value is the maximum number of titles displayed on the display device 3. For example, if the maximum number of titles to be displayed is set to 10 as shown in FIG. Is 1
It is displayed on the display device 3 with a limit of 0 cases. It is assumed that the ten titles are set in advance such that the retrieval target documents are stored in the order of storage, or the top ten titles that are prioritized are displayed.

After that, in step 303, the keyword input section 24 is activated, and the character string forming the keyword can be input from the input device 2. User input device 2
From here, the character string that constitutes the keyword is input, but here, the keyword character string that is input is set to a plurality, and the input keyword character string is obtained by processing the input plurality of keywords under the OR condition or the AND condition. There is also a device having a function of searching based on. After inputting the keyword character string, the user clicks the return key or the search button with a mouse or the like. This allows step 30
At 4, the search processing unit 25 is activated to execute the search processing.
This search processing is performed by searching the external storage device 4 for a document classified by the input keyword or a document including the keyword, and outputting the number of answers of the corresponding document, The title character string is read from the external storage device 4 and stored in the title character string buffer 29. When the search process of the search processing unit 25 is completed, the number-of-responses output unit 26 displays the number of responses n in step 305 on the screen of the display device 3 via the display unit 28 as shown in FIG.

In step 306, the number-of-responses output unit 26 determines whether or not the number of responses n is greater than 0. If the number of responses is greater than 0, the process proceeds to step 307 to set the currently displayed title number counter i to 0, and n is If it is 0, the process ends. When the process of step 307 is completed, the title output unit 27 is activated next in step 308 to display the i-th title stored in the title character string buffer 29 on the display device 3.
After the output to the screen of, the present display title number counter i is incremented by +1 in step 309. Further, the title output unit 27 determines in step 310 whether or not the currently displayed title number counter i is less than or equal to the number of answers n. . In step 311, the title output unit 27 determines whether or not the currently displayed title number counter i is less than or equal to the maximum title display number m, and if less, returns to step 308 to repeat the title display processing, but if not, If so, the process ends. FIG. 5 is an example in which the number of answers and titles are displayed on the screen of the display device 3 by the title output unit 27. In this case, the number of answers is 20
The number of titles displayed is 10 which is the maximum display limit. When any one of the titles displayed on the screen of the display device 3 is designated by the user via the input device 2, the control device 1 stores the corresponding document in the external storage device 4.
The content of this document is displayed on the screen of the display device 3.

According to the present embodiment, up to the maximum title display number m designated by the user, the title of the retrieved document is displayed on the display device 3 even if the response number n is larger than the above-mentioned m. be able to. That is, even if the number of replies exceeds the title display capability of the display device 3 due to the search process, the number of titles (m) set by the user is displayed on the display device 3 and the content of the document can be viewed. Therefore, it is possible to solve the problem that the search work cannot proceed unless the number of answers is narrowed down as in the conventional case. Further, even when the number of answers n is large, only the titles of the number (m) designated by the user are displayed, so that the titles can be displayed for a short time, and the search processing can be made efficient by this amount. Further, even in a device that displays the title display order by changing the old or new of the searched document or the priority, the document with the low priority or the old document is not displayed,
It is possible to reduce the burden on the user and improve the document search efficiency. Further, since the capacity of the screen of the display device 3 and the memory for display may be designed so as to correspond to the maximum number m of displayed titles, the cost of the device can be set to an appropriate value.

When the number of responses n is larger than the maximum number of titles displayed m, the user sequentially displays the remaining titles other than the title initially displayed on the display device 3 by a command from the input device 2. However, it does not diminish the above effects.

[0016]

As described above, according to the document search apparatus of the present invention, the user can arbitrarily set the maximum number of titles to be displayed, so that a part or all of the titles of the searched documents can be surely set. Since it can be displayed,
The document search work can be advanced without narrowing down the number of responses to the display capacity or less, and the operability of the device can be significantly improved.
