[2. Explanation of operation]
Next, specific operations of the server apparatus 1 according to the present embodiment will be described with reference to the flowchart of FIG.

First, the control unit 11 of the server device 1 determines whether a search request from the terminal device 3 has been acquired (step S101). Specifically, the control unit 11 determines whether or not the communication unit 15 has acquired a search request based on a query specified by the user in the terminal device 3.
If it is determined that the search request has been acquired (step S101: YES), the process proceeds to the next step S102.
On the other hand, when it is determined that the search request has not been acquired (step S101: NO), the process of step S101 is repeated until the search request is acquired.

Next, the control unit 11 acquires a search result based on the search request acquired in step S101 (step S102). Specifically, the control unit 11 executes a search process in response to the search request acquired in step S101, and acquires a search result that matches the specified query.
That is, the control unit 11 functions as a search unit that acquires search results that match the search request based on the search request from the terminal device 3.

  Next, the control unit 11 determines whether or not the coupon target product is included in the search result acquired in step S102 (step S103). Here, the coupon target product is a product submitted as a target of a time-limited coupon by each store. A time-limited coupon is a coupon whose expiration date is determined in advance, and is a coupon that can inform the user of the remaining time of the expiration date and can motivate purchase. The coupon information of the coupon target product is stored in the storage unit 14 at the time of submission from each store. Coupon information of coupon target products submitted from each store is stored in the storage unit 14 in a form aggregated as a coupon DB 141.

  As shown in FIG. 5, the coupon DB 141 is stored in the storage unit 14 in a state in which product information (product name) is associated with a keyword, a coupon content, an expiration date, and a start condition. For example, in the example illustrated in FIG. 5, when the product information is “humidifier OO”, the keyword associated with the product information is “humidifier”, the coupon content is “30% off”, and the expiration date is “10”. The start condition is “30 inventory or more by March 20”. If the product information is “humidifier ΔΔ”, the keyword associated with the product information is “humidifier”, the coupon content is “25% off”, the expiration date is “10 minutes”, and the start condition is “ It is “more than 20 in stock by March 20th”. The keyword may be set by each store at the time of submission from each store, or may be automatically extracted from the product information.

The control unit 11 refers to the coupon DB 141, and there is a coupon target product when there is a coupon target product that matches the specified query and the keyword associated with each coupon target product. It is determined that For example, in the example illustrated in FIG. 5, when the designated query is “humidifier”, it is determined that the coupon target product is included.
When it is determined that the coupon target product is included (step S103: YES), the process proceeds to step S105.
On the other hand, if it is determined that the coupon target product is not included (step S103: NO), only the web page displaying a list of the search results acquired in step S102 is distributed to the terminal device 3 (step S104), and processing is performed. Exit.

Next, the control unit 11 determines whether the coupon target product included in the search result satisfies a predetermined start condition (step S105). Specifically, the control unit 11 refers to the coupon DB 141 to determine whether or not each coupon target product included in the search result satisfies a start condition for a timed coupon that is individually associated. .
That is, the control unit 11 functions as a first determination unit that determines whether or not the start condition of the time-limited coupon associated with the coupon target product included in the search result acquired by the search unit is satisfied.
The control unit 11 determines that the start condition is satisfied when at least one coupon target product satisfies the start condition. For example, in the example illustrated in FIG. 5, it is determined that the start condition is satisfied when “stock is 30 or more by March 20”.
When it is determined that the predetermined start condition is satisfied (step S105: YES), the process proceeds to step S106.
On the other hand, if it is determined that the predetermined start condition is not satisfied (step S105: NO), only the web page displaying a list of the search results acquired in step S102 is distributed to the terminal device 3 (step S104), and processing Exit.
In addition, even if the validity of the timed coupon has already been lost even if the start condition is satisfied, such as when the stock has expired or the expiration date has passed, the search result obtained in step S102 is displayed. Only the web pages to be displayed in a list may be distributed to the terminal device 3 and the process may be terminated.

Next, the control part 11 distributes the web page which contains the coupon object goods which added the coupon information for displaying a time-limited coupon as a search result to the terminal device 3 by the communication part 15 (step S106). The coupon information is information including, for example, a discount rate (off rate) of the product, the remaining time of the expiration date, and the like.
That is, when the control unit 11 determines that the start condition is satisfied by the first determination unit, the control unit 11 includes a web page including a coupon target product to which coupon information for displaying a timed coupon is added as a search result. It functions as a distribution means for distributing to the device 3.
The web page distributed to the terminal device 3 is displayed on the display unit 33 of the terminal device 3 as a search result screen as shown in FIG.

As shown in FIG. 6, the search result screen includes a search box 331 in which the user can input a query, a search button 332 for confirming the keyword input and making a search request, and a search request based on the input keyword. A product list display unit 333 that displays a list of compatible products, and a coupon display unit 334 that displays a coupon with a time limit when the coupon target product is displayed on the product list display unit 333. Composed. FIG. 6 is a search result screen when “humidifier” is entered as a keyword in the search box 331 and the search button 332 is pressed, and the product list display unit 333 displays four products A1 to A4. The coupon display unit 334 displays time-limited coupons C1 and C2 corresponding to the coupon target products A1 and A2, respectively.
In addition, as for the display order of the product displayed on the product list display unit 333, it is preferable that the coupon target product is given priority, and when there are a plurality of coupon target products, the longer remaining time of the timed coupon is given priority. For example, in the example illustrated in FIG. 6, the coupon target products A1 and A2 are given priority over the non-coupon target products A3 and A4, and the coupon target products A1 and A2 are given priority to the products A1 with a long remaining time of the time-limited coupons C1 and C2. Is done.

Next, the control part 11 determines whether the page acquisition request | requirement of the product page of the coupon object product from the terminal device 3 was acquired (step S107). Specifically, the control part 11 is the said coupon object goods by having selected the coupon object goods (including the time-limited coupon of the said coupon object goods) displayed on the web page (search result screen) in the terminal device 3. It is determined whether a page acquisition request for the product page is acquired. In the present embodiment, it is assumed that a page acquisition request is generated when the timed coupon C1 is clicked on the search result screen illustrated in FIG.
If it is determined that a page acquisition request has been acquired (step S107: YES), the process proceeds to the next step S108.
On the other hand, if it is determined that a page acquisition request has not been acquired (step S107: NO), the process of step S107 is repeated until a page acquisition request is acquired.
If a page acquisition request for a product page of a product that is not a coupon target is acquired, only the product page of the product is distributed to the terminal device 3 and the process ends.

Next, the control unit 11 determines whether or not the time-limited coupon of the coupon target product requested for page acquisition is within the expiration date (step S108). Specifically, the control unit 11 refers to the coupon DB 141 and determines whether the time-limited coupon of the coupon target product requested for page acquisition is within the expiration date. For example, in the example illustrated in FIG. 5, when the count is within “10 minutes” from the start, it is determined that it is within the expiration date. The condition for starting the count may be, for example, the timing at which the search result is displayed, or may be a case where the inventory becomes a predetermined number or less or a predetermined date has passed.
That is, based on the page acquisition request of the product page of the coupon target product when the coupon target product displayed on the web page is selected in the terminal device 3, the control unit 11 requests the coupon target product for the page acquisition. It functions as a second determination means for determining whether or not the time-limited coupon is within the expiration date.
If it is determined that it is within the expiration date (step S108: YES), the process proceeds to the next step S110.
On the other hand, if it is determined that it is not within the expiration date, that is, it is outside the expiration date (step S108: NO), only the product page of the coupon target product requested for page acquisition is delivered to the terminal device 3 (step S109). The process ends.

Next, the control part 11 delivers the product page of the coupon object product which added the coupon information for displaying a time-limited coupon to the terminal device 3 (step S110). Specifically, the control unit 11 distributes the product page of the coupon target product requested for page acquisition to the terminal device 3. In addition, the control unit 11 refers to the referrer of the product page (URL of the link source page (in this embodiment, the time-limited coupon C1 in FIG. 6)), and displays the coupon information embedded in the parameter part of the referrer. Extracted and distributed to the terminal device 3.
That is, the control unit 11 uses the product page of the coupon target product to which the coupon information for displaying the time-limited coupon is added as the distribution unit when the second determination unit determines that the expiration date is within the expiration date. Delivered to the terminal device 3.
The product page distributed to the terminal device 3 is displayed on the display unit 33 of the terminal device 3 as a product page screen as shown in FIG.

As shown in FIG. 7, the product page screen includes a product display unit 335 that displays the coupon target product requested for page acquisition, and a product description unit that explains detailed information (for example, sales price and shipping cost) of the coupon target product. 336, a purchase button 337 for confirming the purchase of the coupon target product, and a coupon display unit 338 for displaying a time-limited coupon of the coupon target product. FIG. 7 is a product page screen when the coupon target product A1 (coupon C1) is selected in the search result screen of FIG. 6, and the coupon display unit 334 displays the coupon C1 of the coupon target product A1 following the search result screen. Is displayed.
Therefore, for example, when the transition of the coupon target product to the product page is not from the search result screen (see FIG. 6) but from another page, coupon information cannot be extracted even if the referrer is referred to. No timed coupon is displayed on the product page.

[3. effect]
As described above, the information search device (server device 1) according to the present embodiment is based on the search request from the terminal device 3 and the search unit (control unit 11) that acquires the search result that matches the search request. First determination means (control unit 11) for determining whether or not the start condition of the timed coupon associated with the coupon target product included in the search result acquired by the search means is satisfied, and the first Distribution unit (control unit) that distributes, to the terminal device 3, a web page including a coupon target product to which coupon information for displaying a timed coupon is added when the determination unit determines that the start condition is satisfied. 11).
Therefore, according to the information search device according to the present embodiment, the application of the time-limited coupon can be received only when the coupon target product is searched, so that the coupon purpose search can be promoted. In addition, since the coupons are time-limited, since the coupons cannot be applied unless the purchase is decided within the expiration date, the user's willingness to purchase can be stimulated. As a result, the use of coupons can be promoted.

In addition, the information search device according to the present embodiment, based on the page acquisition request of the product page of the coupon target product when the coupon target product displayed on the web page in the terminal device 3 is selected, the page acquisition request 2nd determination means (control part 11) which determines whether the time-limited coupon of the made coupon object goods is within an expiration date. In addition, the distribution unit distributes the product page of the coupon target product to which the coupon information for displaying the timed coupon is added to the terminal device 3 when the second determination unit determines that the expiration date is within the expiration date. To do.
Therefore, according to the information search device according to the present embodiment, the application of the time-limited coupon can be applied only when the searched coupon target product is selected on the search result screen. Since the coupon cannot be applied unless the purchase is decided, the user's willingness to purchase can be further stimulated. As a result, the use of coupons can be further promoted.

[4. Others]
As mentioned above, although concretely demonstrated based on embodiment which concerns on this invention, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.

  For example, in the said embodiment, although an expiration date is arbitrarily set for every coupon object goods, it is not limited to this. For example, the expiration date may be set so as to increase as the price of the coupon target product increases. This makes it possible to secure a user's examination time for a higher-priced product, while a low-priced product can shorten the expiration date and stimulate the user's willingness to purchase. can do.

Moreover, in the said embodiment, although the coupon content of a time-limited coupon is made into the fixed thing, it is not limited to this. For example, under the control of the control unit 11, the coupon content of the timed coupon may be changed based on the timing of the page acquisition request.
For example, in the above embodiment, a fixed off rate is set for each coupon target product, but the present invention is not limited to this. For example, the control unit 11 may lower the off rate of the time-limited coupon as time elapses, that is, as the remaining time of the expiration date becomes shorter.
Thereby, since an off rate can be made high, so that it buys early, a user's willingness to purchase can be stimulated and an advertising effect can be improved.

  Moreover, in the said embodiment, although one keyword is matched with one coupon object goods, it is not limited to this. That is, a plurality of keywords may be associated with one coupon target product. For example, in the example illustrated in FIG. 8, three keywords “humidifier”, “aroma diffuser”, and “humidifier XX” are associated with one product “humidifier XX”.

In addition, when a plurality of keywords are associated with one coupon target product, the control unit 11 determines the content of the coupon information based on the content of the keyword that matches the search request (query). May be.
For example, as shown in FIG. 8, when a product “humidifier XX” is searched for “humidifier”, which is a general name of the product, “30% off” is set. If the name is “humidifier XX”, the search may be “20% off”. This is because when searching with a general name, it is considered that the willingness to purchase for a specific product ("humidifier XX" in the above example) is lower than when searching with a specific name. This is because it is effective to increase the off-rate and stimulate the user's willingness to purchase.
In addition, as shown in FIG. 8, when searching for “aroma diffuser” for one product “humidifier OO”, “aroma oil” is attached instead of discounting the product price. May be. That is, the content of the time-limited coupon in the present invention is not limited to the discount on the product price, and may be any content as long as it can return the profit to the buyer.

In addition, when a plurality of keywords are associated with one coupon target product, the control unit 11 determines the content of the coupon information based on the number of keywords that match the search request (query). Also good.
For example, when a product “humidifier OO” is searched with two words “humidifier aroma diffuser”, the off rate may be lowered. This is because the greater the number of queries at the time of search, the higher the willingness to purchase for the product, so the product can be purchased even if the off-rate is lowered.

In the above-described embodiment, the product page and the time-limited coupon are displayed at the same time on the product page screen, that is, the time-limited coupon is displayed at the timing of transition to the product page. It is not a thing. For example, instead of displaying at the timing of transition to the product page, it may be displayed when the user's interest is increased, i.e., purchase intention can be felt. Examples of the case where the customer is willing to purchase include, for example, the length of time during which a product page is displayed, the number of times that the product page or a product page of a similar product is searched for display, and the like.
Thereby, when a user's willingness to purchase can be sufficiently felt, coupon display can be performed in a form that further stimulates the willingness to purchase, so that the advertising effect can be further enhanced.

  In addition, when further applying the time-limited coupon of the present invention to a product for which a coupon different from the present invention is set, the off-rate of the time-limited coupon of the present invention is higher than the preset off rate. The content of the coupon information may be determined so as to be higher.

  Moreover, each aspect shown in this application can also be grasped | ascertained as a method, a program, etc. For the method and program categories, “means” shown in the device category is appropriately replaced with “process” or “step”, for example. In addition, the order of processes and steps is not limited to the one directly specified in the present application, and the order can be changed, or a part of processes can be collectively or changed to be executed one by one at any time.

  In addition, the detailed configuration of each device constituting the server device and the terminal device and the detailed operation of each device can be changed as appropriate without departing from the scope of the present invention.
