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.

  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 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, each item information 210 of the corresponding product list 201 initially displays a product image, a product name, the number of impressions, a price, and a store name. Here, in the shopping system S, after the user performs some action on the listed products, when any link in the other search result link group 203 is selected, each item information 210 includes: More detailed information is displayed. In other words, in each case information 210, in addition to the product image, the product name, the number of impressions, the price, and the store name, information that is not initially displayed among some information about the product (that is, the product image, At least one item name, the number of impressions, the price, and the store name are additionally displayed. For example, as shown in FIG. 4, each item information 210 is additionally displayed with a product description 215. The product description 215 is a description of the product.

  Specifically, the action for the product includes selection of the product link 211, selection of the impression link 212, selection of the store link 213, and selection of the comparison button 204. That is, the action for the product means an operation related to the product displayed in a list. Accordingly, operations that are not related to the product itself, such as selection of any link in the sort condition link group 202, selection of a link in the other search result link group 203, and operation of the scroll bar 300 are included in the action for the product. I can't.

  It can be considered that the fact that there is some action on the listed products means that the user is at least interested in the products for which the action is performed. 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 no action has been taken, once the user has taken an action on any product, there are other products that are of interest to the user in addition to the product that the user has taken action on. If it exists, it is estimated that the possibility that the user thinks increases.

  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. Therefore, it is appropriate to display a more detailed display regarding the product only when the user is considered interested once.

  In FIG. 4, a description of the product is additionally displayed. Thus, the information to be additionally displayed may be changed according to the content of the user's action. For example, in the shopping system S, a detailed page corresponding to the user action is displayed. Therefore, any information displayed on the details page may be additionally displayed. Specifically, after the product link 211 is selected and the product detail page is displayed, for example, a description of the product is additionally displayed. Further, after the impression link 212 is selected and the impression detail page is displayed, for example, one impression is additionally displayed. Further, after the store link 213 is selected and the store detail page is displayed, for example, store guide information is additionally displayed. In addition, after the comparison button 204 is selected and the comparison details page is displayed, information that can be easily compared, for example, shipping costs, payment methods, and the like are additionally displayed. Further, after a plurality of types of detail pages are displayed, information displayed on each page may be additionally displayed one by one.

  Moreover, in the shopping system S, when displaying the search result page which displays more detailed information, the display number of a search result is made smaller than the initial display number (initial value of the display number). For example, as shown in FIG. 3, one case information 210 for ten cases was initially displayed. However, after the user performs an action, one case information 210 for five cases is displayed as shown in FIG. Is displayed. One reason is that the vertical length of one page is not increased, and the burden of the scroll operation is not increased.

  How much the number of display items is reduced is arbitrary, but for example, the number of display items may be determined so that the vertical length of the corresponding product list 201 is the same before and after the additional information is displayed. . Then, the amount of scroll operation for browsing the corresponding product list 201 is the same before and after the change in the number of display items. As a method of reducing the number of displayed items, a certain number of values can be subtracted from the initial number, or a predetermined percentage can be reduced from the initial number. When the initial value of the display number can be changed by user setting, if the predetermined percentage is reduced, the scroll operation amount for browsing the corresponding product list 201 before and after the change of the display number is about the same. Become.

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

  FIG. 5 is a sequence diagram illustrating a processing example of the shopping system S according to the present embodiment. FIG. 5 is a processing example when the initial value of the number of display cases is 10.

  As shown in FIG. 5, 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 items from the 1st item to the 10th item without additional information to the user terminal 2 (step S14). The user terminal 2 displays the received search result page (step S15).

  Here, when the user selects the product link 211 of any product from the corresponding product list 201 on the search result page (step S16), the user terminal 2 that has detected the operation transmits a product detail request to the shopping server 1. (Step S17). Then, the shopping server 1 transmits a product detail page corresponding to the product detail request to the user terminal 2 (step S18). The user terminal 2 displays the received product detail page (step S19).

  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 S20), the user terminal 2 that has detected the operation is selected. The search result return request (an example of the return request in the present invention) is transmitted to the shopping server 1 (step S21). Then, the shopping server 1 transmits to the user terminal 2 a search result page that additionally displays the product description 214 as a list of 10 corresponding products from the first to the tenth (Step S22). The user terminal 2 displays the received search result page (step S23). As described above, in the present embodiment, after the detailed page is displayed by the user's action, the number of items of information displayed per corresponding product when the display returns to the display of the search result page (in the present embodiment, , Product description 214) increases.

  When the user selects the next result link 230 (step S24), 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 S25). Then, the shopping server 1 transmits, to the user terminal 2, a search result page that additionally displays the product description 214 as a list of corresponding products for 5 items from the 11th to the 15th (Step S <b> 26). The user terminal 2 displays the received search result page (step S27).

  Here, when the user selects the next result link 230 without performing any action on the corresponding products displayed in the list (step S28), the user terminal 2 that has detected the operation shopping the next result request. It transmits to the server 1 (step S29). Then, the shopping server 1 transmits to the user terminal 2 a search result page that displays a list of 10 corresponding products from the 15th to the 25th without additional information (step S30). The user terminal 2 displays the received search result page (step S31). Thus, in this embodiment, if there is no action from the user, the number of display items per page returns to the initial value.

  A specific product search example will be described. It is assumed that the user searches for a digital camera having specifications desired by the user. 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 one after another to display an inspection result page on which a list of digital cameras is displayed. Then, the user thinks that he / she will have the desired specifications, and selects the digital camera he is interested in from the list to display the details page. Thereafter, returning to the inspection result page, when the user selects the next result link 230, a search result page for additionally displaying additional information is displayed. Digital cameras with the same specifications are considered to have the same price. Since more detailed information is displayed in the list of digital cameras that have the same price as the digital camera that displayed the detail page, the user can compare each digital camera to some extent on the search result page. .

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

  FIG. 6 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. 6 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 “no action” in the control flag F (step S56). In addition, the system control unit 20 sets an initial value D to the display number N per search result page (step S57). 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. Further, the control flag F indicates whether or not there is an action from the user for the listed products. When there is no action, “no action” is set in the control flag F, and when there is an action, “with action” is set in the control flag F.

  When the system control unit 20 initializes the variables, based on the product ID set in the generated list, the system control unit 20 stores the default display data of the products from the L-th item to the L + N−1-th item according to the display priority. Obtained from the DB 102 and the product DB 103 (step S58). The product display data is information displayed on the search result page. The default display data is data corresponding to information displayed from the beginning in each piece of information 210 on the search result page among the data registered in the database. Name, number of impressions, price, and store name. The image, the product name, the number of impressions, the price, and the store name as data items are examples of the first item in the present invention.

  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). After completing this process, 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 S61). 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 a next result request (step S53: next result), the system control unit 20 adds the display number N to the display start number L (step S62). 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 determines whether or not “with action” is set in the control flag F (step S63). At this time, if “no action” is set in the control flag F (step S63: NO), the system control unit 20 proceeds to step S56. That is, the system control unit 20 transmits a search result page without additional information to the user terminal 2.

  On the other hand, when “with action” is set in the control flag F (step S63: YES), the system control unit 20 makes the display number N smaller than the initial value D. Specifically, the system control unit 20 calculates the following equation (1).

N = D × β (1)
Here, β is a preset coefficient that satisfies 0 <β <1. The example in FIG. 4 is an example in which β = 0.5.

  Next, the system control unit 20 determines the default display data and additional display data of the products from the L-th item to the L + N−1-th item according to the display priority order based on the product ID set in the generated list. It acquires from store DB102 and goods DB103 (Step S65). The additional display data is data corresponding to additional information among data registered in the database. Note that the item of additional data is an example of the second item in the present invention. After completing this process, the system control unit 20 proceeds to step S59. That is, the system control unit 20 displays the additional information and transmits a search result page in which the number of display items per page is smaller than the initial value to the user terminal 2.

  In step S53, when the received request is a detailed request (an example of a page transmission request in the present invention) (step S53: details), the system control unit 20 sets “with action” to the control flag F ( Step 66). 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.

  Next, the system control unit 20 transmits a product detail page corresponding to the received request to the user terminal 2 that has transmitted the request (step S67). 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 S65. 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. In step S65, the system control unit 20 transmits a search result page including additional information.

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 S69), 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 is registered for each item. Search for product information that satisfies the search conditions from the product information including the displayed display data, and display data corresponding to the number of items corresponding to the initial value of the number of items displayed as the default. The search result page for displaying the display data of the item is transmitted to the user terminal 2, and the next result request for requesting data corresponding to information other than the information for which the display data is displayed on the search result page is received from the user terminal 2. In response to the next result request, display data corresponding to information different from the information corresponding to the display data displayed on the search result page transmitted earlier is displayed. To send a Shimesuru search results page to the user terminal. Further, the system control unit 20 detects the user operation related to the display data displayed on the previously transmitted search result page by the user terminal 2 after the search result page is transmitted until the next result request is received. It is determined whether or not it has been done. Specifically, the system control unit 20 determines whether a detailed request has been received from the user terminal 2. If the system control unit 20 determines that the detailed request has been received after the search result page is transmitted until the next result request is received, the additional display data is added to the default display data. The search result page to be displayed is transmitted to the user terminal 2. In addition, when the system control unit 20 determines that the detailed request has been received every time the next result request is received, a search result page that displays additional display data in addition to the default display data is displayed as the current user terminal. 2 to send.

  Accordingly, the number of items of display data displayed per search item as a search result increases. Thereby, when the user is interested, the user can obtain more information from the search result. Therefore, since the user does not have to perform an operation for displaying the detailed contents, it is possible to reduce the viewing burden on the information that attracts the user's interest.

  In addition, when the system control unit 20 determines that the detailed request has been received after the search result page is transmitted until the next result request is received, the search result displayed on the search result page transmitted this time The number of displayed items is less than the number of displayed search results displayed on the previously transmitted search result page.

  Therefore, when the data amount of the display data of each product displayed as the search result increases, the number of search results displayed per page of the search result decreases, thereby suppressing the length of one page from becoming long. Can do.

  In addition, when the system control unit 20 determines that the detailed request has been received after the search result page is transmitted until the next result request is received, the search result displayed on the search result page transmitted this time Is β times the number of search results displayed on the previously transmitted search result page (where 0 <β <1).

  Accordingly, since the number of search results displayed per page of search results is reduced by a predetermined ratio, it is possible to suppress an increase in the length of one page.

  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. When there is a product that the user is interested in among the products that are currently displayed, it is estimated that there is a higher possibility that there is a product that the user will be interested in among the products for which display data is displayed next. Therefore, it is possible to reduce the browsing burden related to information that attracts the user's interest.

  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, so that the user who searches for the product based on one of the cheap prices is attracting the user's interest. The burden of browsing information can be reduced.

  In addition, when the sorting conditions are set in the order of the price of the product, the search results are displayed in the order of the price of the product, so that the user who searches for the product based on the price height as one of the criteria is interested in the user. It is possible to reduce the burden of browsing related information.

  In addition, the system control unit 20 receives a detailed request transmitted from the user terminal 2, transmits a detailed page to the user terminal 2 in response to the detailed request, and receives a search result return request from the user terminal 2. When a search result return request is received, a search result page is transmitted to the user terminal 2. At this time, the system control unit 20 transmits a search result page that displays additional display data in addition to the default display data to the user terminal 2 this time.

  Therefore, when returning from the detailed page to the display of the search result page, the number of items of data displayed per one corresponding product increases. Therefore, when the user is interested, the user can obtain more information from the search result. Therefore, since the user does not have to perform an operation for displaying the detailed contents, it is possible to reduce the viewing burden on the information that attracts the user's interest.

  Further, when the system control unit 20 transmits a detailed page to the user terminal 2 in response to the detailed request, items of display data additionally displayed on the search result page to be transmitted next are displayed on the transmitted detailed page. Match any item with the data.

  Accordingly, the display data item additionally displayed per product as a search result matches any data item included in the displayed detail page. Therefore, the user can confirm the data of the item he / she is interested in from the search result.

  When the system control unit 20 determines that the detailed request has not been received after the search result page is transmitted and before the next result request is received, the search result page for displaying the default display data is displayed. It transmits to the user terminal 2.

  Therefore, after the number of items of display data displayed for each corresponding product increases, if there is no user action, the number of items of display data displayed for each corresponding product returns to the default. The fact that the user does not perform any operation on the product for which the display data is displayed can be considered that there is no product that attracts the user's interest in the product. In this case, since the number of items of the display data is restored, the time for browsing the search result when the user loses interest can be reduced.

  Note that if the user has an interest once, the interest can be considered to continue. Therefore, even when it is determined that the detailed request has not been received between when the search result page is transmitted and when the next result request is received, the system control unit 20 adds additional information to the default display data. A search result page for displaying the display data may be transmitted to the user terminal 2. In this case, since the number of items of display data to be displayed remains increased, it is possible to reduce the browsing burden related to information that attracts the user's interest.

  Further, when the display returns to the display of the search result page from the detailed page, it is not necessary to increase the number of items of data displayed per one corresponding product.

  Moreover, in the said embodiment, the item of the information additionally displayed for every applicable goods in the search result page was in agreement with the item of the information displayed on the detailed page displayed by the user's action. However, the item of information to be additionally displayed may be other than the item of information displayed by the user action as long as it is an item related to the corresponding product. In the search result page, items of information displayed from the beginning for each corresponding product 210 may be items other than the items described in the above embodiment as long as they are items related to the corresponding product. In addition, the item of information displayed from the beginning on the corresponding product 210 and the item of information additionally displayed may each be one item or a plurality of items.

  In the above embodiment, after the number of display results per page of the search result is once reduced by the user's action, the number of display results per page of the search result does not decrease any further after that. It was. However, the number of displayed items may be gradually reduced in response to the user's action. For example, in the process of FIG. 6, a control counter C is introduced as a variable. The control counter C indicates the number of times the next result request is transmitted when there is an action for the corresponding product listed on the search result page. The initial value of the control counter C is 0. Then, when “with action” is set in the control flag F in step S63 (step S63: YES), the system control unit 20 adds 1 to the control counter C. Then, the system control unit 20 calculates the number of display cases N by calculating the following formula (2), for example, and proceeds to step S59.

N = D × β ^ C (2)
On the other hand, a plurality of processes can be considered when “no action” is set in the control flag F in step S63 (step S63: NO). As an example, the system control unit 20 returns the control counter C to the initial value 0, and proceeds to step S58. That is, the system control unit 20 returns the display number to the initial value. Further, the number of displayed items may be larger than the initial value. As another example, the system control unit 20 subtracts 1 from the control counter C, calculates Expression (2), and proceeds to step S59. That is, the system control unit 20 gradually brings the number of display items closer to the initial value.

  Moreover, the aspect of the reduction | decrease in the number of displays is not limited to this. For example, the number of display items may decrease in proportion to the control counter C. In this case, instead of calculating Expression (2), the system control unit 20 calculates the display number N by calculating the following Expression (3), for example.

N = D + C × α (3)
Here, α is a preset coefficient that satisfies α ≧ 1. Further, the coefficient α or β may be changeable by a user setting.

  Further, a lower 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 decrease below the lower limit value. Moreover, this lower limit value may be changeable by user setting.

  Further, even when the number of items of display data displayed per corresponding product on the search result page is increased by the user's action, the number of display per page may not be reduced.

  Moreover, in the said embodiment, when the next result link 230 was selected and operated by the user in the search result page, the number of items of display data displayed per search item as the search result was increased. For example, when a link that specifies a page number is selected as a search result, or when a link that displays “Previous” is selected, the number of items of display data displayed per corresponding product is increased. Also good.

  In the above embodiment, in step S28, after the detailed page is displayed by the user's action, the user selects the next result link 230 and then does not perform any action on the corresponding products for the five listed items. When the next result link 230 is selected, the shopping server 1 transmits to the user terminal 2 a search result page that displays a list of 10 corresponding products without additional information (step S30). That is, in this embodiment, if there is no action from the user, the number of display items per page returns to the initial value. However, if there is no action from the user, in step S30, the shopping server 1 may transmit a search result page displaying a list of corresponding products for 10 items or 5 items with additional information to the user terminal 2.

  In addition, the present invention is not limited to the above-described embodiment. For example, the user operation related to the display data displayed on the search result page is between the transmission of the search result page and the reception of the next result request. When the determination means determines that the product is not detected by the search means, when the user asks to display a list of products different from the products displayed in the current corresponding product list 201, the currently displayed search result Information having a larger number of items than the page may be displayed without additional items.

  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 transmitting means transmits a first data group composed of a predetermined number of data among the data groups corresponding to the information group searched by the searching means to the user terminal 2, and second data When it is determined that the user operation has been detected by the determination unit, the data transmission unit transmits the second data group including the number of pieces of data larger than the number of pieces of data constituting the first data group. May be.

  If there is no action on the listed products, it can be considered that the user is not interested in the listed products 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. In other words, when the user does not perform any operation on the display data displayed on the search result page, the user is not interested by increasing the number of display data displayed on the search result page to be transmitted next. While it is possible to reduce product search results and operations for requesting undesired search results, if the user performs any operation on the display data displayed on the search results page, the search results to be sent next By increasing the number of items (information amount) of the display data displayed on the page, it is possible to view detailed information on products that the user is interested in as a list. Therefore, the user can browse the search result efficiently.

  Moreover, in the said embodiment, although operation which displays a detailed page as user operation of this invention was made into the action with respect to applicable goods, even if it is operation other than this, a user is interested in applicable goods, An operation that allows the user to consider the corresponding product as desired may be an action for the corresponding product. For example, in the search result page, when the user places the pointer displayed on the screen on the product link 211 for a certain time or more, information related to the product corresponding to the product link 211 is displayed in a pop-up manner. The user operation at this time may be an action for the corresponding product. In addition, an operation for simply selecting the check box 214 may be an action for the corresponding product. In addition, an operation for registering any of the corresponding products displayed in a list as a user's favorite may be an action for the corresponding product. In the case of these actions, for example, when the system control unit 20 generates an HTML document of the search result page, a notification message that notifies the shopping server 1 that an action has occurred (another example of operation notification in the present invention). Is embedded in the HTML document of the search result page.

  Moreover, in the said embodiment, although the information search device of this invention was applied with respect to the server apparatus which searches the information of the goods sold and transmits a search result to a user terminal, information other than the information of goods The information search device of the present invention may be applied to a device that searches for information. For example, when the information search device of the present invention is applied to a search engine or the like, information to be searched is, for example, a Web page, image data, a news article, or the like. The user operation in this case is, for example, an operation for displaying a searched Web page, or an operation for displaying an image that has been searched and displayed as a thumbnail in its original size.
