Description

  The present invention relates to an information processing apparatus, an information processing program, and an information processing method for processing information.

  For example, a form search system in a financial business has a client device and a search server connected to the client device via a network or the like. When the operator instructs execution of the form search, the client device requests the search server to obtain a search result. The search server executes a form search in response to a request from the client device and acquires a search result. Then, the client device acquires the search result from the search server, and displays the acquired search result list screen on the display unit.

  In addition, as a method of search processing, for example, in parallel with inputting a search expression for a plurality of items by interactive processing, a given search expression is executed for each input item and the result is obtained. There is a document search processing method that performs an intermediate save as an item-by-item bitmap, and performs a set operation using the item-by-item bitmap after input of all items and an intermediate save of the bitmap for each item are completed. (For example, refer to Patent Document 1).

  Also, for example, when the number of hits exceeds the set number of hits, a secondary search is performed by a logical product with one other keyword added, and when the number of hits is less than or equal to the set number of hits, the number of text hits There is a text search method for storing and extracting a set number of extracted texts in descending order of the number of hits, and outputting the contents of each text (for example, see Patent Document 2).

Japanese Patent Laid-Open No. 11-306203 JP-A-8-314950

  In a search system in which a client device acquires a search result from a search server, the search result acquired from the search server is stored in a buffer of the client device. Although the buffer size is set in advance, if the number of search results is large and the buffer size required to store the search results is larger than the preset buffer size, buffer expansion processing is executed. .

  However, since the buffer expansion process takes time, when the number of search results is large, there is a possibility that the time until the search result list screen is displayed on the display unit may become long. This problem can also occur in other information processing apparatuses used for search processing.

  In view of such a point, an object of the present invention is to shorten the time required for displaying a search result on a display unit.

Based on the number of search results acquired by executing the search result acquisition means for acquiring from the search execution means, the buffer means for storing the search results displayed on the display means, and the number of search results acquired by the search result acquisition means Buffer size setting means for setting the buffer size of the buffer means.

  Further, the information processing program displays a search screen including a search condition input field on the display means, and displays a search condition input field when the display control unit detects escape of focus from the search condition input field. The search execution means responds to the search result number acquisition request by the search result request means for requesting the search execution means to acquire the search result number of the data search based on the search condition entered in The number of search results acquired by executing the data search is changed to the search result acquisition means acquired from the search execution means, the buffer means for storing the search results displayed on the display means, and the number of search results acquired by the search result acquisition means. Based on this, it functions as buffer size setting means for setting the buffer size of the buffer means.

  Also, in this information processing method, when the computer displays a search screen including a search condition input field on the display means and detects escape of focus from the search condition input field, the search condition input in the search condition input field The search execution means is requested to obtain the number of search results for data search based on the search results, and the search execution number is retrieved by the search execution means performing a data search in response to the request for obtaining the search result number. Based on the number of search results acquired from the means, the buffer size of the buffer means for storing the search results displayed on the display means is set.

  According to the information processing apparatus, the information processing program, and the information processing method of the disclosure, it is possible to reduce the time taken until the search result is displayed on the display unit.

[Step S <b> 101] The search result request unit 121 acquires the search conditions input in the search condition input fields 131 to 134 of the search screen 130 from the display control unit 110.
[Step S102] The search result request unit 121 determines whether the search condition acquired from the display control unit 110 is equal to the content of the search condition table 122a stored in the search condition storage unit 122. If they are equal, the search result request unit 121 ends the process. If they are not equal, the search result request unit 121 advances the process to step S103.

[Step S103] The search result request unit 121 updates the search condition table 122a based on the search condition acquired from the display control unit 110.

When the search condition is not input in all of the search condition input fields 131 and 132, the search result request unit 121 ends the process.

  [Step S105] The search result request unit 121 requests the search server 30 to acquire the number of search results for the form search based on the search condition acquired from the display control unit 110. In response to this request, the search server 30 executes a form search and acquires the number of search results.

[Step S106] The search result acquisition unit 124 acquires the number of search results from the search server 30.
[Step S107] The buffer size setting means 126 determines whether or not the buffer size required to store the search results for the number of search results acquired by the search result acquisition means 124 is larger than the preset maximum buffer size. If larger, the buffer size setting means 126 advances the process to step S109. If not larger, the buffer size setting means 126 advances the process to step S108.

  [Step S108] The buffer size setting unit 126 sets the buffer size of the buffer unit 125 based on the number of search results acquired by the search result acquisition unit 124, and ends the process.

  [Step S109] The buffer size setting means 126 determines whether or not the current buffer size of the buffer means 125 is the same as the preset maximum buffer size. If they are the same, the buffer size setting unit 126 ends the process. If they are not the same, the buffer size setting unit 126 advances the process to step S110.

[Step S110] The buffer size setting unit 126 sets the buffer size of the buffer unit 125 to the maximum buffer size, and ends the process.
Next, the flowchart shown in FIG. 8 will be described. The following processing is started when the display control unit 110 detects that the search button 135 on the search screen 130 is pressed. Here, it is assumed that the search result acquisition unit 124 acquires the number of search results from the search server 30 in advance.

  [Step S201] The search result request unit 121 determines whether or not the number of search results acquired by the search result acquisition unit 124 is equal to or less than a preset maximum number of acquisitions. If it is equal to or less than the maximum number of acquisitions, the search result request unit 121 advances the process to step S202. If the number is not less than the maximum number of acquisitions, the search result request unit 121 advances the process to step S203.

  [Step S202] The search result requesting unit 121 obtains search results for the number of search results in the form search based on the search conditions input in the search condition input fields 131 to 134 of the search screen 130. To request.

[Step S204] The search result acquisition unit 124 acquires the search result from the search server 30. The acquired search result is stored in the buffer means 125.
[Step S205] The display control unit 110 generates a list screen of search results based on the search results stored in the buffer unit 125, displays the list on the monitor 21, and ends the process.

  Next, a document search procedure according to the second embodiment will be described with reference to FIGS. FIG. 9 is a sequence diagram illustrating a first example of a form search procedure according to the second embodiment. FIG. 10 is a sequence diagram illustrating a second example of the form search procedure according to the second embodiment. 11 and 12 are diagrams illustrating screen transition states according to the second embodiment. FIG. 13 is a diagram illustrating a transition state of the search condition table according to the second embodiment.

  First, the first example shown in the sequence diagram of FIG. 9 will be described. As an initial state, a search screen 130 shown in FIG. In this example, the maximum buffer size is a size that can store 200 search results, and the maximum number of search results acquired is 200.

[Step S301] The search result acquisition control means 120 prepares a search condition table 122a shown in FIG.
[Step S302] As shown in FIG. 11B, when the focus 130a exits from the search condition input field 131 by the operation of the operator, the display control means 110 detects this and the search result acquisition control means 120 detects it. Notice.

  [Step S303] The search result acquisition control means 120 updates the search condition table 122a as shown in FIG. Here, the search condition column corresponding to the identifier (1) indicating the search condition input column 131 is changed from “null” to “form”.

  At this stage, since the search condition field corresponding to the identifier (2) indicating the search condition input field 132 which is an essential search condition input field is “null”, the search result acquisition control unit 120 includes the search server 30. The search result number is not requested for.

Thus, unnecessary access to the search server 30 can be suppressed by checking the input status in the required search condition input field using the search condition table 122a.
[Step S304] As shown in FIG. 11C, when the focus 130a escapes from the search condition input field 132 by the operation of the operator, the display control means 110 detects this and the search result acquisition control means 120 detects it. Notice.

  [Step S305] The search result acquisition control means 120 updates the search condition table 122a as shown in FIG. Here, the search condition column corresponding to the identifier (2) indicating the search condition input column 132 is changed from “null” to “Suzuki”.

  [Step S306] As shown in the search condition table 122a shown in FIG. 13C, the search conditions corresponding to the identifiers (1) and (2) indicating the search condition input fields 131 and 132 as the essential search condition input fields are shown. Since all the entries have been input, the search result acquisition control means 120 requests the search server 30 to acquire the number of search results for the form search based on the input search conditions.

[Step S307] The search server 30 executes a search. Here, it is assumed that the number of search results is 200.
[Step S308] The search server 30 notifies the search result acquisition control means 120 of the number of search results (200). At this stage, the search server 30 does not output the search result to the search result acquisition control means 120. Thereby, it can suppress that load will be applied to communication between the client apparatus 100 and the search server 30. FIG.

  [Step S309] Since the buffer size for the number of search results (200) acquired from the search server 30 is not larger than the maximum buffer size (for 200), the search result acquisition control unit 120 uses the buffer size of the buffer unit 125. Is set to the size corresponding to the number of search results (200). That is, the search result acquisition control unit 120 generates the buffer unit 125 having a storage area with a size corresponding to the number of acquired search results (200).

  In addition, since the process of said step S306-S309 is performed by an asynchronous process, the input to the following search condition input column and the press of various buttons are effective in the search screen 130, without waiting for a response.

  [Step S310] As shown in FIG. 11D, when the focus 130a escapes from the search condition input field 133 by the operation of the operator, the display control means 110 detects this and the search result acquisition control means 120 detects it. Notice.

  [Step S311] The search result acquisition control means 120 updates the search condition table 122a as shown in FIG. Here, the search condition column corresponding to the identifier (3) indicating the search condition input column 133 is changed from “null” to “7/13”.

  [Step S312] As shown in the search condition table 122a shown in FIG. 13D, there are search conditions corresponding to the identifiers (1) and (2) indicating the search condition input fields 131 and 132 which are the essential search condition input fields. Since all the entries have been input, the search result acquisition control means 120 requests the search server 30 to acquire the number of search results for the form search based on the input search conditions.

[Step S313] The search server 30 executes a search. Here, it is assumed that the number of search results is 100.
[Step S314] The search server 30 notifies the search result acquisition control means 120 of the number of search results (100).

  [Step S315] The search result acquisition control unit 120 sets the buffer size of the buffer unit 125 to a size corresponding to the number of search results (100). That is, the search result acquisition control unit 120 regenerates the buffer unit 125 having a storage area having a size corresponding to the number of acquired search results (100 cases) after releasing the storage area occupied by the buffer unit 125.

Note that the processes in steps S312 to S315 are performed asynchronously.
[Step S316] As shown in FIG. 12A, when the search button 135 is pressed by an operation by the operator, the display control unit 110 detects this and notifies the search result acquisition control unit 120 of it.

  [Step S317] Since the number of retrieved search results (100) is equal to or less than the maximum number of retrieved items (200), the retrieval result acquisition control unit 120 performs search for the number of search results based on the input search condition. The search server 30 is requested to acquire the search result.

[Step S318] The search server 30 outputs the search results (100) to the search result acquisition control means 120.
[Step S319] The search result acquisition control unit 120 notifies the display control unit 110 of acquisition of the search result.

  [Step S320] The display control means 110 displays a list screen 140 of search results for 100 items, as shown in FIG. Here, since the buffer size of the buffer unit 125 is set in advance to a size necessary for displaying the search result, it is not necessary to perform an expansion process or the like of the buffer unit 125, and the search result list screen 140 is displayed on the monitor 21. It can be displayed in a short time.

  Next, a second example shown in the sequence diagram of FIG. 10 will be described. As an initial state, the search screen 130 shown in FIG. 11B is displayed on the monitor 21, and a search condition table 122a shown in FIG. 13B is prepared. In this example, the maximum buffer size is a size that can store 200 search results, and the maximum number of search results acquired is 200.

  [Step S401] As shown in FIG. 11C, when the focus 130a escapes from the search condition input field 132 by the operation of the operator, the display control means 110 detects this and the search result acquisition control means 120 detects it. Notice.

  [Step S402] The search result acquisition control means 120 updates the search condition table 122a as shown in FIG. Here, the search condition column corresponding to the identifier (2) indicating the search condition input column 132 is changed from “null” to “Suzuki”.

  [Step S403] As shown in the search condition table 122a shown in FIG. 13C, the search conditions corresponding to the identifiers (1) and (2) indicating the search condition input fields 131 and 132 as the essential search condition input fields are shown. Since all the entries have been input, the search result acquisition control means 120 requests the search server 30 to acquire the number of search results for the form search based on the input search conditions.

[Step S404] The search server 30 executes a search. Here, it is assumed that the number of search results is 500.
[Step S405] The search server 30 notifies the search result acquisition control means 120 of the number of search results (500).

  [Step S406] Since the buffer size for the number of search results (500) acquired from the search server 30 is larger than the maximum buffer size (for 200), the search result acquisition control unit 120 sets the buffer size of the buffer unit 125. Set the maximum buffer size (for 200). That is, the search result acquisition control unit 120 generates the buffer unit 125 having a storage area of the maximum buffer size (for 200 cases).

  In addition, since the process of said step S403-S406 is performed by an asynchronous process, the input to the following search condition input column and the press of various buttons are effective in the search screen 130, without waiting for a response.

  [Step S407] As shown in FIG. 11D, when the focus 130a escapes from the search condition input field 133 by the operation of the operator, the display control means 110 detects this and the search result acquisition control means 120 detects it. Notice.

  [Step S408] The search result acquisition control means 120 updates the search condition table 122a as shown in FIG. Here, the search condition column corresponding to the identifier (3) indicating the search condition input column 133 is changed from “null” to “7/13”.

  [Step S409] As shown in the search condition table 122a shown in FIG. 13D, there are search conditions corresponding to the identifiers (1) and (2) indicating the search condition input fields 131 and 132 which are the essential search condition input fields. Since all the entries have been input, the search result acquisition control means 120 requests the search server 30 to acquire the number of search results for the form search based on the input search conditions.

[Step S410] The search server 30 executes a search. Here, it is assumed that the number of search results is 300.
[Step S411] The search server 30 notifies the search result acquisition control means 120 of the number of search results (300).

  Here, the buffer size for the number of search results (300) acquired from the search server 30 is larger than the maximum buffer size (for 200), and the current buffer size (for 200) is the maximum buffer size. Since this is the same as (for 200), the search result acquisition control unit 120 does not set the buffer size.

Further, the processes in steps S409 to S411 are performed in an asynchronous process.
[Step S412] As shown in FIG. 12A, when the search button 135 is pressed by an operation by the operator, the display control unit 110 detects this and notifies the search result acquisition control unit 120 of it.

  [Step S413] Since the number of retrieved search results (300) is not less than or equal to the maximum number of retrieved (200), the retrieval result acquisition control unit 120 determines the maximum number of retrieved documents for the form search based on the input search condition ( The search server 30 is requested to obtain search results for 200).

Thus, by requesting acquisition of search results for the maximum number of acquisitions, it is possible to suppress receiving an enormous amount of search results.
[Step S414] The search server 30 outputs 200 search results of the search results (300) to the search result acquisition control means 120.

[Step S415] The search result acquisition control unit 120 notifies the display control unit 110 of acquisition of the search result.
[Step S416] The display control means 110 displays a list screen 140 of 200 search results on the monitor 21 as shown in FIG. Here, since the buffer size of the buffer unit 125 is set in advance to a size necessary for displaying the search result, it is not necessary to perform an expansion process or the like of the buffer unit 125, and the search result list screen 140 is displayed on the monitor 21. It can be displayed in a short time.

  [Step S417] As shown in FIG. 12C, when the next button 142 is pressed by the operation of the operator, the display control means 110 detects this and notifies the search result acquisition control means 120. .

  [Step S418] The search result acquisition control means 120 requests the search server 30 to acquire search results for the maximum number of acquisitions (200) in the form search based on the input search conditions.

[Step S419] The search server 30 outputs the remaining 100 search results to the search result acquisition control means 120.
[Step S420] The search result acquisition control unit 120 notifies the display control unit 110 of acquisition of the search result.

[Step S421] The display control means 110 displays a list screen 140 of search results for 100 cases shown in FIG.
As described above, in the client apparatus 100, when the search result request unit 121 detects that the focus 130 a has escaped from the search condition input fields 131 to 134 of the search screen 130, the display control unit 110 detects the search condition input field 131. To 134, the search server 30 is requested to acquire the number of search results of the form search based on the search conditions input to. The buffer size setting unit 126 sets the buffer size of the buffer unit 125 based on the number of search results acquired by the search result acquisition unit 124 from the search server 30.

  According to this configuration, before the operator presses the search button 135 to instruct execution of the search, the buffer size of the buffer unit 125 is set in advance to a size necessary for storing the search result. be able to. For this reason, it is not necessary to perform the expansion process of the buffer means 125 after the search button 135 is pressed by the operator, so that the time taken to display the search result list screen 140 on the monitor 21 can be shortened. it can.

  Furthermore, in the client device 100, since the buffer size of the buffer unit 125 is set based on the number of search results acquired by the search result acquisition unit 124, it can be set to the minimum necessary size. That is, the storage area occupied by the buffer unit 125 among the storage areas included in the client device 100 can be reduced, so that the remaining storage areas can be used for other processes. Thereby, the processing performance of the client apparatus 100 can be improved.

  Further, in the client device 100, the search result request unit 121 determines whether or not the search condition is input in all of the search condition input fields 131 and 132 that are the essential search condition input fields, and determines that the search conditions are input. In this case, the search server 30 is requested to acquire the number of search results for the form search based on the search conditions respectively input in the search condition input fields 131 to 134.

  Thereby, since the client apparatus 100 accesses the search server 30 for the first time when the search condition is input to all of the essential search condition input fields, unnecessary access to the search server 30 can be suppressed.
