[3. Display search results]
Next, a display mode of a search result when a product is searched in the shopping system S will be described with reference to FIGS. 3 and 4.

  When searching for a product, the shopping server 1 transmits, as a search result, a web page indicating a list of products that satisfy the search condition input by the user (hereinafter referred to as “corresponding product”) to the user terminal 2. This Web page is referred to as a “search result page”. FIG. 3 is a diagram illustrating a screen display example of a search result page by the user terminal 2.

  As shown in FIG. 3, on the search result page, a corresponding product list 201, a sort condition link group 202, another search result link group 203, a comparison button 204, and the like are displayed.

  The corresponding product list 201 displays a list of products that satisfy the search conditions. Specifically, the corresponding product list 201 includes a plurality of pieces of single item information 210. One item information 210 indicates information for one item of the corresponding product. The one item information 210 includes a product image, a product link 211, an impression link 212, a product price, a store link 213, and a check box 214. The product link 211 is a link (hyperlink) that displays the name of the product corresponding to the link. The impression link 212 is a link that displays the number of impressions of the product registered by the user who purchased the product corresponding to the link. The store link 213 is a link that displays the name of the store that sells the product corresponding to the link. The check box 214 is a check box for selecting a product to be compared when comparing a plurality of products.

  When the product link 211 is selected by the user, a transition is made to a Web page that displays detailed information on the product corresponding to the link. This Web page is referred to as a “product detail page”. On the product detail page, for example, information such as a product name, an image relating to one or a plurality of products, a description of the product, a price of the product, a settlement method, a shipping fee, a shipping method, and an inquiry destination are displayed.

  When the impression link 212 is selected by the user, a transition is made to a Web page that displays the impression of the product corresponding to the link. This Web page is referred to as an “impression detail page”. On the impression detail page, for example, a nickname, an evaluation value, a posting date, an impression sentence, and the like of a poster who has posted an impression are displayed.

  When the store link 213 is selected by the user, a transition is made to a Web page that displays detailed information on stores that sell products corresponding to the link. This Web page is referred to as a “store detail page”. On the store detail page, for example, a store name, store guide information, a link to a product detail page of each product sold by the store, a settlement method, a shipping fee, a shipping method, and the like are displayed.

  The product detail page, the impression detail page, and the store detail page are generated by the shopping server 1 based on information registered in the store DB 102 and the product DB 103 and stored in the storage unit 15.

  The sort condition link group 202 includes a plurality of links for the user to select a sort condition. The sort condition indicates a condition for sorting priorities for displaying products satisfying the search condition in the search result. Sorting conditions include, for example, the standard, the order of the price of goods, the order of the price of goods, the new arrival order, and the order of the number of impressions. Note that the standard as the sort condition means, for example, that the corresponding products are sorted in the searched order. When one of the links in the sort condition link group 202 is selected by the user, the display priority of the corresponding product is sorted according to the sort condition corresponding to the selected link. Then, according to the sorted priorities, the list of corresponding products displayed in the corresponding product list 201 is rearranged.

  The other search result link group 203 includes a plurality of links for transitioning to a search result page that displays a list of products different from the products displayed as a list in the current corresponding product list 201 among the products that satisfy the search conditions. Including. For example, when a link for displaying a page number is selected by the user, the screen transitions to a search result page with a page number corresponding to the link. Further, when the next result link 230 displayed as “next” is selected by the user, a transition is made to the search result page next to the currently displayed search result page. For example, when a list of corresponding products from the first to the tenth items is currently displayed, when the next result link 230 is selected, a search result page displaying a list of the corresponding products after the eleventh item is displayed. Transition. In this way, in the display priority order sorted according to the sort condition, a list of the corresponding products that are continuously displayed in the priority order with the corresponding products currently displayed as a list is displayed.

  When the comparison button 204 is selected by the user, a transition is made to a Web page that displays information on a plurality of products for which the check box 214 is selected. This Web page is referred to as a “comparison detail page”. On this comparison detail page, for example, the name, image, price, description of the product, store name, shipping fee, payment method, etc. of the selected product are displayed in a list.

  The product detail page, the impression detail page, the store detail page, and the comparison detail page are collectively referred to as a “detail page”. The detailed page is a Web page that displays information related to one or more products among the products displayed in the corresponding product list 201, and at least one piece of information that is not displayed in the one item information 210. This is a Web page to be displayed.

  When the entire search result page cannot be displayed on one screen, a scroll bar 300 is displayed on the screen of the user terminal 2. When the scroll bar 300 is operated, the search result page is scrolled. Note that the scroll bar 300 itself does not constitute a search result page.

  In such a search result page, the number of corresponding products displayed in the corresponding product list 201 is referred to as “display number”. The initial value of the display number is predetermined in the shopping system S. The initial value of the display number can be changed by user setting.

  When there is no product that attracts interest or a desired product among the corresponding products displayed in a list on the search result page, for example, the user selects the next result link 230 to display another list. If the number of displayed items does not change with the initial value, if the number of products that meet the search condition is considerably larger than the number of displayed items, the user can link to the next result link until an interesting product or desired product is found. 230 must be selected many times. The efficiency of browsing search results is reduced due to the time and effort required for this selection operation and the time required for the selection operation.

  Therefore, in the shopping system S, the time elapsed from when a certain search result page is displayed until another search result page is displayed (hereinafter referred to as “elapsed time”) is less than or equal to a predetermined time. The number of displayed items increases.

  The short time from when one search result page is displayed until another search result page is displayed means that the time for browsing the list of products is short. When the time for browsing the list of products is short, it can be considered that the products displayed in the list are not interested by the user or there is no product desired by the user. In this case, the user selects the next result link 230 and displays a list different from the list displayed so far. At this time, it is presumed that the user is more likely to be in a psychological state that the possibility that the user is interested or the possibility that the desired product does not exist this time will be higher than the possibility that the user exists. In such a psychological state, it is considered that the user tends to browse the list of products in a shorter time than the beginning. In such a case, if the number of display items increases, more information can be browsed in a short time. In addition, the number of times of selecting the next result link 230 can be reduced.

  When there is a product that the user is interested in among the displayed products, or there is a product that the user desires, the user can select the product link 211, the impression link 212, the store link 213, or the comparison button. Select 204 to display the details page. Thereafter, the user may browse another search result page. At this time, the time until a different search result page is displayed becomes longer by the time the user browses the detail page. In addition, even if the user does not display the detailed page, it is considered that when there is a product of interest among the products displayed in the list, the user tends to look at the list carefully (take time). In such a case, it is considered that the user is more likely to be in a psychological state that is more likely to be interested or have the possibility that the desired product still exists than the possibility that the product does not exist. In such a psychological state, when a user browses another search result page, the user tends to browse the list of products at the same time as the first or more time than the first. Conceivable. In such a case, there is no need to increase the number of displayed items. That is, of the total effort and time required for browsing the search result, the burden of selecting the next result link 230 and the specific gravity of the time are reduced. Therefore, even if the number of times of selecting the next result link 230 is not reduced, there is no particular influence. It is because it is considered. Moreover, when a user browses a list of products over time, it is considered that it is easier for the user to see if the number of display items does not increase.

  Even when the user browses the detail page, the time until another search result page is displayed may be short. Also in this case, the number of displayed items increases. In this case, since the time when the user browsed the detail page is short, it can be considered that the product on which the detail page is displayed was not the product that attracted the user's interest after all.

  The time used as a threshold for determining whether to increase the number of display cases is referred to as a threshold time. The threshold time is preset. The length of the threshold time is arbitrary, but for example, it may be determined based on the result of a subjective experiment or the like by actually causing the subject to use the shopping system S. The threshold time may be changeable by user setting. In the shopping system S, the threshold time is increased in proportion to the number of display results per page of search results. This is to cope with an increase in the browsing time of the search result by the user according to the number of displayed items.

  Further, since the shopping server 1 needs to measure the elapsed time, the elapsed time actually measured in the present embodiment is that the shopping server 1 transmits the search result page and then receives the search result page. This is the time until a request for another search result page from the user terminal 2 is received.

  Next, an outline of the operation of the shopping system S relating to the control of the number of displays on the search result page will be described.

  FIG. 4 is a sequence diagram illustrating a processing example of the shopping system S according to the present embodiment. FIG. 4 is an example of processing when the initial value of the number of display items is 10 and the number of display items is increased by twice. FIG. 4 is a processing example when the threshold time is 5 seconds per 10 display cases.

  As shown in FIG. 4, in the user terminal 2, the user inputs search conditions (step S11). Search conditions include, for example, keywords, product price ranges, product categories, and the like. At this time, it is also possible to select a sort condition. Then, the user terminal 2 transmits a search request including the input search condition to the shopping server 1 (step S12).

  The shopping server 1 executes a search process based on the search condition included in the received search request (step S13). And the shopping server 1 transmits the search result page which displays the list of the applicable goods for 10 cases from the 1st case to the 10th case to the user terminal 2 (step S14). The user terminal 2 displays the received search result page (step S15).

  When the user selects the next result link 230 (step S16), the user terminal 2 that has detected the operation transmits a next result request (an example of a transmission request in the present invention) to the shopping server 1 (step S17). ). Here, if the shopping server 1 determines that the next result request has been received within 5 seconds from the transmission of the search result page in step S14 (step S18), the corresponding products for 20 items from the 11th to the 30th item. A search result page for displaying a list of is transmitted to the user terminal 2 (step S19). That is, the shopping server 1 increases the number of display items. The user terminal 2 displays the received search result page (step S20).

  When the user further selects the next result link 230 (step S21), the user terminal 2 that has detected the operation transmits a next result request to the shopping server 1 (step S22). If the shopping server 1 determines that the next result request has been received within 10 seconds from the transmission of the search result page in step S19 (step S23), the corresponding products for 40 items from the 31st item to the 70th item are received. A search result page for displaying a list of is transmitted to the user terminal 2 (step S24). That is, the shopping server 1 further increases the display number. The user terminal 2 displays the received search result page (step S25).

  Here, when the user selects any product, for example, the 35th product link 211 from the corresponding product list 201 on the search result page (step S26), the user terminal 2 that has detected the operation makes a product detail request. It transmits to the shopping server 1 (step S27). Then, the shopping server 1 transmits a product detail page corresponding to the product detail request to the user terminal 2 (step S28). The user terminal 2 displays the received product detail page (step S29).

  Here, when the user selects a button displayed as “return” on the Web browser or a button displayed as “return” on the product detail page (step S30), the user terminal 2 that has detected the operation is selected. Then, a search result return request is transmitted to the shopping server 1 (step S31). Then, the shopping server 1 displays the search result page having the same content as the search result page transmitted in step S24 (search result page displaying a list of 40 corresponding products from the 31st to the 70th item) to the user terminal. 2 (step S32). The user terminal 2 displays the received search result page (step S33).

  When the user selects the next result link 230 (step S34), the user terminal 2 that has detected the operation transmits a next result request to the shopping server 1 (step S35). Here, when the shopping server 1 determines that 20 seconds have elapsed after the transmission of the search result page in step S24 (not step S32) and has received the next result request (step S36), the shopping server 1 is the 71st to 80th case. A search result page displaying a list of the corresponding products up to 10 is transmitted to the user terminal 2 (step S37). That is, the shopping server 1 returns the display number to the initial value. The user terminal 2 displays the received search result page (step S38).

  A specific product search example will be described. It is assumed that the user searches for a digital camera that satisfies the conditions desired by the user and that is as cheap as possible. In this case, the search condition is a digital camera, and the sort condition is in ascending order of price. When the search is executed under this condition, it is assumed that the digital camera body and the digital camera accessory are included in the search result as corresponding products. Here, it is assumed that the price of the accessory is lower than the price of the digital camera body. Then, only accessories are displayed on the first search result page. Therefore, the user selects the next result link 230 and increases the number of display items of the corresponding product from 10 to 20 and 40. When a desired digital camera is found at the 67th case, the user browses the product detail page of the product. In this case, the number of times the user has selected the next result link 230 is two. On the other hand, if the number of displayed items remains unchanged, the user has to select the next result link 230 six times.

  As described above, in the shopping system S, the number of display items gradually increases, so that the number of times to select a link of the other search result link group 203 can be reduced.

[4. Operation of shopping system]
Next, the operation of the shopping system S will be described with reference to FIG.

  FIG. 5 is a flowchart illustrating a processing example of the system control unit 20 of the shopping server 1 according to the present embodiment. The process of FIG. 5 is started when the shopping server 1 waits for a request from the user terminal 2, for example.

  First, the system control unit 20 determines whether a request is received from the user terminal 2 (step S51). At this time, if the request has not been received (step S51: NO), the system control unit 20 performs the determination process in step S51 again.

  On the other hand, when receiving a request from the user terminal 2 (step S51: YES), the system control unit 20 specifies the user of the user terminal 2 that has transmitted the received request (step S52). For example, the user accesses the shopping server 1 by operating the user terminal 2 in advance, and logs in to the shopping site by inputting his / her member ID and password. By this login, the shopping server 1 issues a session ID to the user terminal 2 and manages various information including the member ID as session information in association with the session ID. Moreover, the shopping server 1 transmits session ID to the user terminal 2 as a cookie, for example. Since the session ID is included in the subsequent request from the user terminal 2 to the shopping server 1, the system control unit 20 can specify which user the request is from.

  When specifying the user, the system control unit 20 determines what type of the received request is (step S53). At this time, if the received request is a search request (step S53: search), the system control unit 20 executes a search process (step S54). Specifically, the system control unit 20 searches the product DB 103 based on the search condition included in the received search request. Next, the system control unit 20 extracts information such as a product ID, a price, a sales start date / time, and the number of impressions of the product satisfying the search condition from the product DB 103. Then, the system control unit 20 generates a search result list based on the extracted information, and stores the search result list in the storage unit 15 in association with the session ID. In addition, on the list of search results, the information on each corresponding product is arranged in the order of search, for example.

  After completing the search process, the system control unit 20 initializes variables included in the specified user session information. Specifically, the system control unit 20 sets 1 to the display start number L (step S55). Further, the system control unit 20 sets 0 to the control counter C (step S56). Here, the display start number L indicates the number of the first product among the corresponding products displayed in a list on the search result page. This product number indicates the display priority when the search results are sorted. A smaller value of this number indicates a higher priority. The control counter C indicates the number of times that the elapsed time is equal to or less than the threshold time.

  When the variable is initialized, the system control unit 20 calculates the display number N per search result page (step S57). Specifically, the system control unit 20 calculates the following equation (1).

N = D × β ^ C (1)
Here, D is an initial value of the display number. Further, β is a preset coefficient that satisfies β> 1. Note that the example of FIG. 4 is an example in which β = 2.

  When the display control number N is calculated, the system control unit 20 displays the display data of the products from the Lth item to the L + N−1th item according to the display priority order based on the product ID set in the generated list (in the present invention). An example of data displayed when the product information is searched is acquired from the store DB 102 and the product DB 103 (step S58). The product display data is information displayed on the search result page, and specifically includes an image, a product name, a price, a store name, and the like. Next, the system control unit 20 generates an HTML document of the search result page based on the acquired display data (step S59). Next, the system control unit 20 transmits the generated HTML document of the search result page to the user terminal 2 that has transmitted the request (step S60). Next, the system control unit 20 determines whether or not the received request is a search result return request (step S61). At this time, if the received request is not a search result return request (step S61: NO), the system control unit 20 acquires the current time as the transmission time of the search result page (step S62). When the received request is a search result return request (step S61: YES), or when the process of step S62 is completed, the system control unit 20 proceeds to step S51.

  In step S53, when the received request is a sort request (step S53: sort), the system control unit 20 executes a sort process (step S63). The sort request is transmitted from the user terminal 2 when a link of the sort condition link group 202 on the search result page is selected. In this sort request, the sort condition selected by the user is set. In the sort process, the system control unit 20 sorts the information on the products set in the search result list according to the sort condition included in the received sort request. That is, the system control unit 20 rearranges the display priorities of the corresponding products in the order indicated by the sort conditions. After completing the sorting process, the system control unit 20 proceeds to step S55. That is, the system control unit 20 transmits to the user terminal 2 a search result page that displays a list from the first item to the D-1 items of the corresponding product sorted under the new sorting condition.

  In step S53, when the received request is the next result request (step S53: next result), the system control unit 20 acquires the current time as the reception time of the next result request (step S64). The next result request is transmitted from the user terminal 2 when the next result link 230 is selected. Next, the system control unit 20 adds the display number N to the display start number L (step S65).

  Next, the system control unit 20 calculates an elapsed time T1 required from when the search result page is transmitted until the next result request is received based on the times acquired in step S62 and step S64 (step S66). ). The elapsed time T1 is a time obtained by subtracting the transmission time of the search result page acquired in step S62 from the reception time of the next result request acquired in step 64. That is, in this embodiment, the time when the system control unit 20 (first data transmission unit) transmits the search result page (first data group) to the user terminal 2 is used as the start time of the elapsed time. Next, the system control unit 20 calculates a threshold time T2 (step S67). Specifically, the system control unit 20 calculates the following formula (2).

T2 = (C + 1) × T (2)
Here, T is a set time in which the number of display cases is set in advance as a threshold time per D cases.

  Next, the system control unit 20 determines whether or not the elapsed time T1 is equal to or less than the threshold time T2 (step S68). At this time, if the elapsed time T1 is greater than the threshold time T2 (step S68: NO), the system control unit 20 proceeds to step S56. That is, the system control unit 20 returns the number of display items per page to the initial value, and transmits the search result page to the user terminal 2.

  On the other hand, when the elapsed time T1 is equal to or less than the threshold time T2 (step S68: YES), the system control unit 20 adds 1 to the control counter C (step S69), and proceeds to step S57. That is, the system control unit 20 transmits the search result page to the user terminal 2 by increasing the number of displays per page by β times the previous time.

  In step S53, when the received request is a detail request (step S53: detail), the system control unit 20 transmits a detail page corresponding to the received request to the user terminal 2 that has transmitted the request ( Step 70). The detail request is a generic term for a product detail request, an impression detail request, a store detail request, and a comparison detail request. The product detail request is a request transmitted from the user terminal 2 when the product link 211 displayed on the search result page is selected. The comment detail request is a request transmitted from the user terminal 2 when the comment link 212 displayed on the search result page is selected. The store detail request is a request transmitted from the user terminal 2 when the store link 213 displayed on the search result page is selected. The comparison detail request is a request transmitted from the user terminal 2 when the comparison button 204 displayed on the search result page is selected. After completing this process, the system control unit 20 proceeds to step S51.

  In step S53, when the received request is a search result return request (step S53: search result return), the system control unit 20 proceeds to step S58. The search result return request is issued when the “return” button of the web browser or the “return” button displayed on the detail page is selected when the detail page is displayed on the screen. It is a request sent by. The system control unit 20 that has shifted to step S58 transmits to the user terminal 2 a search result page having the same content as the search result page transmitted before transmitting the detail page. At this time, the system control unit 20 does not acquire the current time in step S62.

  In step S53, when the received request is not any of the search request, the sort request, the next result request, the detail request, and the search result return request (step S53: other), the received request The process corresponding to is executed (step S71), and the process proceeds to step S51.

  As described above, according to the present embodiment, the system control unit 20 of the shopping server 1 is information on a plurality of products whose data is registered in the product DB 103 built in the storage unit 15 and includes display data. Search for product information that satisfies the search conditions from the product information, and display the search result page that displays the number of display data that corresponds to the initial value of the number of display data corresponding to the searched product information. A next result request that is transmitted to the user terminal 2 and requests data other than the display data displayed on the search result page is received from the user terminal 2 and displayed on the previously transmitted search result page in response to the next result request. A search result page that displays display data different from the display data to be displayed is transmitted to the user terminal. Further, the system control unit 20 determines whether or not an elapsed time from when the search result page is transmitted until the next result request is received is equal to or less than a threshold time. If the system control unit 20 determines that the elapsed time is equal to or less than the threshold time, a search for displaying display data with a larger number of display data than the number of display data displayed on the previously transmitted search result page. The result page is transmitted to the user terminal 2.

  Therefore, by increasing the number of display data items displayed on the search result page to be transmitted next, it is possible to reduce operations for requesting search results for products that the user is not interested in or search results that are not desired. Therefore, the user can browse the search result efficiently. On the other hand, in the conventional shopping server, since the number of display items per page is constant unless changed by the user, browsing of search results has been inefficient.

  In addition, when the system control unit 20 determines that the elapsed time is equal to or less than the threshold time, the number of display data items to be displayed on the search result page to be transmitted next is displayed on the previously transmitted search result page. Β times the number of displayed data.

  Accordingly, since the number of search results displayed per page increases to β, an operation for requesting an undesired search result can be reduced.

  When the system control unit 20 determines that the elapsed time is equal to or less than the threshold time every time the next result request is received, the number of display data displayed on the search result page transmitted this time is transmitted last time. More than the number of display data items displayed on the search result page.

  Therefore, since the number of search results displayed per page gradually increases, it is possible to further reduce operations for requesting search results for undesired products.

  When the system control unit 20 determines that the elapsed time is equal to or less than the threshold time every time the next result request is received, the number of display data displayed on the search result page transmitted this time is transmitted last time. Β times the display data displayed on the search result page.

  Accordingly, since the number of search results displayed per page increases exponentially, it is possible to further reduce operations for requesting search results for undesired products.

  Further, the system control unit 20 receives the sort request including the sort condition from the user terminal 2, sorts the display priority of the corresponding product according to the sort condition, and the display data is displayed on the search result page transmitted last time. A search result page on which display data of the corresponding product having the priority order with the corresponding product is displayed is transmitted.

  Accordingly, the search results of the items having the same or relatively similar items as the sorting criteria according to the sorting condition are displayed together on the terminal device. It is considered that the items with the display priorities are similar in content to the items as compared with the products with non-continuous priorities. Therefore, since the content of the item of the product whose display data is displayed as the next search result is close to the content of the item of the product whose display data was previously displayed as the search result, the current display data is displayed. If there is no product that the user is interested in or desires among the products that are currently displayed, there is no product that the user is interested in or desires among the products for which display data is displayed next. The possibility is likely to be higher. Therefore, it is possible to further reduce operations for requesting search results for undesired products.

  In addition, when the sorting conditions are set in order from the lowest price of the product, the search results are displayed in the order from the lowest price of the product. The operation for requesting the result can be further reduced.

  In addition, when the sorting conditions are set in the order of the product price, the search results are displayed in the order of the product price, so that the user searching for the product based on the price height is one of the criteria for an undesired product. The operation for requesting the search result can be further reduced.

  Further, since the system control unit 20 makes the threshold time used for the determination proportional to the number of display items per page, it is possible to accurately determine whether or not to increase the number of display items.

[Second Embodiment]
In the first embodiment, the time from when the shopping server 1 transmits a search result page until it receives a request for another search result page from the user terminal 2 that has received the search result page is the threshold time. The elapsed time to compare with. On the other hand, in the second embodiment described below, after the user terminal 2 receiving the search result page completes the display processing of the search result page, another search result page from the user terminal 2 is displayed. The time until the request is received is the elapsed time.

  For example, the time required to transmit / receive the search result page may vary depending on the traffic status of the network NW. Further, the time required for displaying the search result page may vary depending on the processing capability of the user terminal 2. In such a case, the time from when the shopping server 1 transmits the search result page to when the search result page is displayed on the user terminal 2 affects the determination for increasing the number of display items per search result page. there is a possibility. Therefore, by setting the measurement start timing of the elapsed time as the timing when the display processing of the search result page is completed, these influences can be eliminated.

  Specifically, when the shopping server 1 generates the search result page, a script that causes the user terminal 2 to acquire the time when the display of the search result page is completed is embedded in the HTML document of the search result page. For example, by describing the onload attribute in the body tag of the HTML document, the script can be executed at the timing when the display of the search result page is completed. Then, for example, the script is described so that the user terminal 2 acquires the time when the script execution is started, and the acquired time is included in the request transmitted to the shopping server 1. The shopping server 1 can calculate the elapsed time based on the time included in the received request. Note that the user terminal 2 may transmit a notification message to the shopping server 1 when the display of the search result page is completed. In this case, the shopping server 1 sets the elapsed time from the time when the notification message is received to the time when the next result request is received.

  FIG. 6 is a flowchart showing a processing example of the system control unit 20 of the shopping server 1 according to the present embodiment. In FIG. 6, the same step numbers are assigned to the same processing as in FIG.

  When acquiring display data from the store DB 102 and the product DB 103 in step S58, the system control unit 20 determines whether or not the received request is a search result return request (step S81). At this time, if the received request is not a search result return request (step S81: NO), the system control unit 20 generates an HTML document of the search result page based on the acquired display data (step S82). . Here, the system control unit 20 embeds a script for acquiring the display completion time of the search result page in the HTML document of the search result page. On the other hand, even when the received request is a search result return request (step S81: YES), the system control unit 20 generates an HTML document of the search result page based on the acquired display data (step S83). However, the system control unit 20 does not embed a script for acquiring the display completion time of the search result page in the HTML document of the search result page. And the system control part 20 will transmit the HTML document of the produced | generated search result page to the user terminal 2 which transmitted the request, after finishing the process of step S82 or S83 (step S60).

  When receiving the HTML document of the search result page, the user terminal 2 analyzes the HTML document and performs display processing of the search result page. If the HTML document includes a script for obtaining the display completion time of the search result page, the user terminal 2 executes the script when the display processing of the search result page is completed, and the display is completed. The current time is acquired as the time. Then, when the next result link 230 is selected by the user, the user terminal 2 transmits a next result request including the acquired display completion time to the shopping server 1. Alternatively, when the user selects the product link 211, the impression link 212, the store link 213, or the comparison button 204 first, the user terminal 2 transmits a detailed request including the acquired display completion time to the shopping server 1. To do.

  When receiving the detailed request (Step S53: Details), the system control unit 20 of the shopping server 1 stores the display completion time included in the detailed request (Step S84). Then, the system control unit 20 transmits a detailed page to the user terminal 2 (step S70). Further, when the system control unit 20 receives the next result request (step S53: next result), the system control unit 20 calculates an elapsed time T1 (step S66). At this time, if the search result page display completion time is included in the next result request, the system control unit 20 calculates the elapsed time T1 based on the display completion time. On the other hand, when the search result page display completion time is not included in the next result request, the system control unit 20 calculates the elapsed time T1 based on the display completion time stored when the detailed request is received. The elapsed time T1 is the display completion time of the search result page included in the next result request acquired in step S53 or the display completion time of the search result page stored in step 84 from the reception time of the next result request acquired in step S64. It is the time taken. That is, in this embodiment, the time when the user terminal 20 completes the display processing of the search result page (first data group) is used as the elapsed time start time.

  As described above, according to the present embodiment, the elapsed time from when the system control unit 20 receives the next result request after the user terminal 2 completes the search result page display processing is equal to or shorter than the threshold time. Therefore, it is possible to more accurately determine the browsing time of the search result by the user.

  In each of the above-described embodiments, the number of display items increases exponentially. However, for example, the mode of increase in the number of display items is not limited to this. For example, the number of display items may increase in proportion to the control counter C. In this case, the system control unit 20 calculates the display number N by calculating, for example, the following equation (2) in step S57 shown in FIG.

N = D + C × α (2)
Here, α is a preset coefficient that satisfies α ≧ 1. Further, the coefficient α or β may be changeable by a user setting.

  In addition, an upper limit value of the number of display cases may be set in advance. That is, the system control unit 20 may perform control so that the number of display items per page does not increase beyond the upper limit. The upper limit value may be changeable by user setting.

  In each of the above embodiments, when the next result link 230 is selected and operated by the user on the search result page, the number of display results per page of the search result is increased. When a link to be specified is selected or a link displayed as “Previous” is selected, the number of search results displayed per page may be increased.

  In each of the above embodiments, the threshold time is increased in proportion to the number of displayed items as the number of displayed items per page of search results increases. However, the threshold time may not be proportional to the number of displayed items. Further, the threshold time may be constant regardless of the number of display results per page of search results.

  In the above-described embodiment, when the shopping server 1 determines that the next result request has been received after the threshold time has elapsed since the transmission of the search result page in step S24 (step S36), the number of display items returned to the initial value. A search result page displaying a list of products is transmitted to the user terminal 2 (step S37). However, the present invention is not limited to the above embodiment. For example, when it is determined that the shopping server 1 has received the next result request after a threshold time has elapsed since the transmission of the search result page in steps S14, S19, and S24, Information that is not initially displayed for each product (for example, product description, product impression, etc.) may be additionally displayed.

  That is, in the information search device (shopping server 1) that searches for information in response to a request from the user terminal 2 and transmits the search result to be displayed on the user terminal 2 to the user terminal 2 via the network in page units, The data transmission means is a first item predetermined as a data group corresponding to the first information group composed of information of a predetermined number of items (for example, product image, product name, price, etc.) The second data transmitting means transmits the second data group when the elapsed time exceeds the threshold time by the determining means. As a data item to be configured, a second item (for example, product detailed information) different from the first item may be added, and the second data group may be transmitted to the user terminal 2.

  The elapsed time from when the first data group is transmitted until the transmission request is received exceeds the threshold time, which means that the user who has been browsing beyond the threshold time has at least displayed search results. You can think of it as having an interest. And since the product which attracts interest exists, it is estimated that there exists a tendency which thinks that there may be a product attracting interest besides this product. In other words, compared to when the next information is requested at or below the threshold time, the user viewing the search result page beyond the threshold time is more likely to be considered by the user that there is a product that the user is interested in. Presumed to be. In such a case, if a certain amount of detailed information is displayed on the search result page, when the user is interested in the list of products, the user has an operation to display the detailed page. Even without this, it is possible to obtain some detailed information. On the other hand, if detailed information is displayed on the search result page from the beginning, a lot of information will be displayed when the user may not be interested, so browsing is troublesome, Since the vertical length becomes longer by the amount of additional information, the burden of scrolling operation increases. Thereby, when the user has requested different information about the display data displayed on the search result page below the threshold time, by increasing the number of display data displayed on the search result page to be transmitted next, While it is possible to reduce the search results for products that the user is not interested in and operations for requesting undesired search results, the user has requested different information for the display data displayed on the search results page beyond the threshold time. In this case, by increasing the number of items (information amount) of the display data displayed on the search result page to be transmitted next, it is possible to browse the detailed information of products that the user is interested in as a list. Therefore, the user can browse the search result efficiently.
