Definitions
- the present invention relates to a technical field of a search device and a search method for performing a search based on a plurality of keywords specified as search conditions.
- search device that performs a search based on a keyword specified by a user.
- search targets include products, services, web pages, and other information.
- the search device When the user specifies a plurality of keywords, the search device generally searches for a search target that matches all the specified keywords. Therefore, the number of search targets to be searched tends to decrease when a plurality of keywords are specified, compared to when only one keyword is specified. Therefore, when the user specifies a plurality of keywords, there may be a case where a sufficient number of search results desired by the user cannot be obtained.
- Patent Literature 1 discloses a technique for extracting a keyword from a sentence input by a user, deleting a keyword that imposes an unnecessarily severe condition from the extracted keywords, and setting a conditional expression for search. It is disclosed. Patent Document 1 discloses a technique for setting a conditional expression by adding a new keyword that replaces a deleted keyword.
- the search conditions used for the search are different from the original search conditions. Therefore, a search target that is not desired by the user may be searched. Further, even if a new keyword is added instead of the excluded keyword, the new keyword and the excluded keyword are not the same. Therefore, also in this case, a search target that is not desired by the user may be searched.
- the present invention has been made in view of the above points, and even when a search target that matches all of a plurality of keywords specified as a search condition does not exist satisfactorily, without changing the search condition, It is an object of the present invention to provide a search device, a search method, a search program, and a recording medium that can obtain a search result desired by a user.
- dividing means for dividing a plurality of keywords specified as search conditions into two child search conditions each including at least one keyword
- the child search Search means for searching for a search object that matches all of the keywords included in the child search condition for each condition, a search object searched by one of the child search conditions, and a search object by the other of the child search conditions
- Extraction means for extracting a combination of search objects having a predetermined relationship with each other from a combination with any one of the search objects.
- the extracted combinations are combinations of search targets that are related to each other. Therefore, even if a search target that matches all of the plurality of keywords specified as the search condition does not exist satisfactorily, the search result desired by the user can be obtained without changing the search condition.
- an aspect in which a plurality of keywords specified as search conditions are divided into three or more child search conditions also belongs to the technical scope of the present invention.
- five keywords a, b, c, d, and e are designated.
- the five keywords are divided into, for example, a child search condition including a and b, a child search condition including c and d, and a child search condition including e.
- a, b, c, and d which are parts of five keywords, are also a plurality of keywords specified as search conditions.
- a plurality of keywords a, b, c, and d are divided into two child search conditions. That is, the process of dividing a plurality of keywords into three or more child search conditions includes the process of dividing the plurality of keywords into two child search conditions.
- the dividing unit searches the number of search targets that match all of the plurality of keywords.
- the plurality of keywords are divided.
- the dividing means is a second number in which the number of search targets searched according to one of the child search conditions is preset. If it is less than one, one of the child search conditions is divided into two grandchild search conditions, and the search means searches for a search object that matches all of the keywords included in the grandchild search condition for each grandchild search condition.
- the extraction means includes any one of the search objects searched by one of the grandchild search conditions, any of the search objects searched by the other of the grandchild search conditions, and a search searched by the other of the child search conditions.
- a combination of search targets having the relation to each other is extracted from a combination with any one of the targets.
- one of the child search conditions is divided into two grandchild search conditions, and each grandchild Search is performed with the search condition. Since the grandchild search condition has fewer keywords than one of the child search conditions, the search target is searched by using the grandchild search condition rather than by using the child search condition. The probability is high. Therefore, the search result desired by the user can be more easily obtained.
- the aspect of dividing the child search condition into three or more grandchild search conditions is also the same as the case of dividing a plurality of keywords specified as search conditions into three or more child search conditions. Belong to the scope.
- the dividing means is a second number in which the number of search targets searched according to one of the child search conditions is preset.
- the child search condition is divided into two grandchild search conditions, and the other grandchild search condition is integrated into the other child search condition.
- a search target that matches all of the keywords included in one and a search target that matches all of the keywords included in the other of the child search conditions are searched, respectively, and the extraction means is configured to search according to one of the grandchild search conditions.
- a combination of search targets having the relation to each other is extracted from a combination of any of the search targets searched and any of the search targets searched by the other of the child search conditions.
- one of the child search conditions is divided into two grandchild search conditions, and the other of the grandchild search conditions Is integrated into the other child search condition. Since the grandchild search condition has fewer keywords than one of the child search conditions, the search target is searched by using the grandchild search condition rather than by using the child search condition. The probability is high. Therefore, the search result desired by the user can be more easily obtained without increasing the number of search targets included in the extracted combination.
- the dividing means is a keyword having the smallest number of search targets to be searched among the plurality of keywords. Is included in the other of the child search conditions, and a keyword not included in the other of the child search conditions is included in one of the child search conditions.
- the one obtained by removing one keyword from the designated search condition becomes one of the child search conditions.
- keywords that are excluded from one of the child search conditions are keywords that have the smallest number of search targets to be searched. Therefore, one of the child search conditions can be brought as close as possible to the designated search condition, and the probability that the search target can be searched by one of the child search conditions can be increased.
- the dividing means uses the plurality of keywords designated for searching for a facility to search for the facility.
- the first child search condition used is divided into the second child search condition not used for facility search, and the search means matches all the keywords included in the first child search condition.
- a facility and an area that matches all the keywords included in the second child search condition are searched for, respectively, and the extracting means includes any one of the facilities searched by the first child search condition, and the first A combination of the facility and the area having the relation with each other is extracted from a combination with any one of the areas searched by the second child search condition.

- the accommodation facility reservation server 1 is a server device that executes various processes related to the accommodation facility reservation site.
- the accommodation facility reservation server 1 is an example of a search device according to the present invention.
- the accommodation facility reservation site is a Web site that accepts reservations for accommodation in accommodation facilities.
- the accommodation facility reservation site is entrusted with accepting reservations from a plurality of accommodation facilities.
- the accommodation facility reservation server 1 transmits, for example, a web page of an accommodation facility reservation site, or performs processing related to a search for an accommodation facility, a reservation for accommodation, and the like.
- the accommodation facility is an example of a search target in the present invention.
- the accommodation facility terminal 2 is a terminal device used by an employee of an accommodation facility entrusted to the accommodation facility reservation site.
- the accommodation facility terminal 2 accesses a server device such as the accommodation facility reservation server 1 based on an operation from an employee or the like. Thereby, the accommodation facility terminal 2 receives and displays the Web page from the server device.
- the accommodation facility terminal 2 incorporates software such as a browser and an e-mail client.
- the employee registers, for example, information on the accommodation facility in the accommodation facility reservation site or confirms the reservation status of the accommodation facility.
- the user terminal 3 is a terminal device of a user who uses the accommodation facility reservation site.
- the user terminal 3 receives the Web page from the accommodation facility reservation server 1 and displays it by accessing the accommodation facility reservation server 1 based on an operation from the user.
- Software such as a browser and an e-mail client is incorporated in the user terminal 3.
- the user can specify a search condition in order to search for an accommodation facility used by the user on the accommodation facility reservation site.
- a keyword can be specified as a search condition.
- the user inputs, as a keyword, a word that briefly represents the accommodation facility condition desired by the user.
- the accommodation facility reservation server 1 searches for an accommodation facility that satisfies the search condition. Specifically, the accommodation facility reservation server 1 searches for an accommodation facility that includes the specified keyword in the accommodation facility name or the detailed information of the accommodation facility. Then, the accommodation facility reservation server 1 transmits the search result page to the user terminal 3.
- the search result page is a Web page that displays a list of searched accommodation facilities. For example, on the search result page, an accommodation facility name, an image of the accommodation facility, a brief description of the accommodation facility, information on an accommodation plan, and the like are displayed for each accommodation facility.
- the accommodation plan is, for example, an accommodation service planned by an accommodation facility.
- a plurality of accommodation plan information may be displayed for each accommodation facility.
- a hyperlink hereinafter referred to as “link” to the accommodation facility page of the searched accommodation facility is embedded in the search result page.
- the accommodation facility page is a Web page on which information related to one accommodation facility is displayed. There are multiple types of accommodation facility pages for each accommodation facility.
- a top page of accommodation facilities a web page on which detailed information on accommodation facilities is displayed, a web page on which a list of accommodation plans is displayed, and the like.
- the user can make a reservation for an accommodation facility by performing a reservation operation on the accommodation facility page.
- a user may have a plurality of conditions required for an accommodation facility to be searched.
- conditions include services that the user wants to receive from the accommodation facility, facilities that the user wants to use, and things that the user wants to do.
- the service and the facility are examples of provision targets provided to the user.
- services, facilities, places, etc. that realize what the user wants to do are examples of the objects to be provided in the present invention.
- search conditions When the user inputs a keyword related to the condition for each requested condition, a plurality of keywords are designated as search conditions.
- the accommodation facility reservation server 1 searches for accommodation facilities that match all of the specified keywords. Therefore, as the number of designated keywords increases, the number of accommodation facilities that match all keywords decreases, or the probability that there are accommodation facilities that match all keywords decreases. Then, the user cannot obtain a sufficient number of search results desired by the user.
- the user can request the accommodation facility reservation server 1 to perform a search again by reducing the number of keywords to be specified. That is, the user respecifies the search condition by excluding some keywords from the plurality of keywords specified first. Alternatively, it may be considered that the accommodation facility reservation server 1 automatically reduces the keyword and performs a search again. However, in this case, the search condition specified first and the newly specified search condition are not the same. Therefore, the search result desired by the user may not be obtained. This is because there is a high probability that the accommodation facilities searched under the new search condition do not include an accommodation facility that satisfies all the conditions that the user first desires.
- the accommodation facility reservation server 1 searches for a combination that matches all of the plurality of keywords specified by the user when combining the accommodation facility and the area. Then, the accommodation facility reservation server 1 causes the user terminal 3 to present the searched combination as a search result to the user.
- the accommodation facility reservation server 1 divides a plurality of keywords specified as search conditions into two search conditions each including at least one keyword.
- One of the two search conditions is an accommodation facility search condition.
- the accommodation facility search condition is a search condition used for searching for an accommodation facility.
- the accommodation facility search condition is an example of a first child search condition in the present invention.
- the other of the two search conditions is a region search condition.
- the area search condition is a search condition that is not used for searching for accommodation facilities. Instead, the region search condition is used for region search.
- the region search condition is an example of a second child search condition in the present invention.
- the accommodation facility reservation server 1 searches for an accommodation facility that satisfies the accommodation facility search condition and also searches for an area that satisfies the region search condition.
- the accommodation facility reservation server 1 extracts a combination of a related accommodation facility and a region from a combination of any of the searched accommodation facilities and any of the searched regions.
- the accommodation facility reservation server 1 determines that the facility and the region are related when the place where the facility is located is within a range predetermined for the region.
- a region is an example of a search target in the present invention.
- the accommodation facility may not be able to provide the object. This is because the user can satisfy the user's request by going to the spot when using the accommodation facility.
- Each region has a spot that may meet the user's requirements. Therefore, a combination of an accommodation facility and a region where the accommodation facility satisfies the accommodation facility search condition including a part of the keywords specified by the user and the region satisfies the region search condition including the remaining keywords. As a whole, the user's requirements are satisfied.
- the accommodation facility reservation server 1 first searches for accommodation facilities that match all of the plurality of keywords specified by the user. And the accommodation establishment reservation server 1 searches the combination of an accommodation establishment and an area, when the number of searched accommodation establishments is less than a threshold value. This is because there is no need to search for a combination of an accommodation facility and a region if there are a certain number of accommodation facilities that satisfy all user requirements. As a result, the accommodation facility reservation server 1 can avoid unnecessary search processing. Further, it is more convenient for the user to satisfy the user's request with one accommodation facility than to satisfy the user's request with a combination of the accommodation facility and the area. This is because the user does not have to go to various places to satisfy his / her request.
- the threshold used at this time is T1. T1 is an example of the first number in the present invention.
- FIG. 2 (a) is a diagram showing a search example of a combination of an accommodation facility and a region.
- the accommodation facility reservation server 1 divides a plurality of keywords specified by the user into an accommodation facility search condition and a region search condition.
- the criteria for division is, for example, whether or not the keyword is related to an object that can be provided by the accommodation facility. That is, the accommodation facility reservation server 1 classifies each of the plurality of keywords as either a keyword related to a target provided by the accommodation facility or a keyword related to a target not provided by the accommodation facility.
- the user wants to use an open-air bath and a bedrock bath, and wants to enjoy mountain climbing, diving and fireworks. Further, it is assumed that the user wants to eat rice cake and wants to have a meal with all-you-can-drink drinks. Therefore, for example, as shown in FIG. 2A, the user designates “open-air bath, mountaineering, all-you-can-drink, diving, fireworks, bedrock bath” as a plurality of keywords. Each word separated by a space is a keyword.
- the plurality of keywords are divided into accommodation facility search conditions including “open-air bath ⁇ all-you-can-drink bedrock bath” and accommodation facility search conditions including “mountain diving fireworks”.
- the target indicated by each keyword in “Open-air bath, all-you-can-drink, bedrock bath” is a target that can be provided by the accommodation facility.
- the target represented by each keyword in “climbing diving fireworks” is generally a target that is not provided at the accommodation facility.
- the accommodation facility reservation server 1 searches for an accommodation facility that matches all the keywords included in the accommodation facility search condition, and searches for an area that matches all the keywords included in the region search condition.
- a set having the searched accommodation facilities as elements is referred to as a “corresponding accommodation facility set”.
- a set having the searched areas as elements is referred to as a “corresponding area set”.
- the accommodation facility reservation server 1 extracts a combination of an accommodation facility and a region that are related to each other from the corresponding accommodation facility set and the corresponding region set.
- the standard for determining whether or not a certain accommodation facility A and a certain region B are related to each other is whether or not the place where the accommodation facility A is located is within a predetermined range for the region B.
- this range is a range in which the user can go from the accommodation facility A to the region B during the trip at the destination.
- the accommodation facility reservation server 1 determines that an area where the accommodation facility is located is an area related to the accommodation facility.
- the accommodation facility reservation server 1 may extend the object related to the accommodation facility to a region adjacent to the region where the accommodation facility is located.
- the accommodation facility reservation server 1 may extend a target related to the accommodation facility to a region close to the region where the accommodation facility is located.
- the accommodation facility reservation server 1 may set a region within a range from a place where the accommodation facility is located to a preset distance as a region related to the accommodation facility.
- AAA inn an AAA inn, a BBB hotel, and a CCC inn are searched for as accommodations that match "open-air bath, all-you-can-drink, bedrock bath". Each of these accommodations is likely to be able to provide an open-air bath, coffee, all-you-can-drink, and bedrock bath.

- T2 is an example of the second number in the present invention.
- FIG. 2B is a diagram showing an example of a change between the accommodation facility search condition and the region search condition.
- the accommodation facility reservation server 1 divides the accommodation facility search condition into the search condition 1 and the search condition 2 according to the type of the object related to the keyword.
- Search condition 1 includes, for example, a keyword related to a bath.
- the search condition 2 includes, for example, keywords related to meals.
- the reason why keywords are classified according to the type of target provided to the user is because, for example, it is considered that there is a suitable place for each type of target. Alternatively, for example, it may be more convenient for the user to provide a plurality of objects belonging to the same type at the same place.
- search condition 1 is a new accommodation facility search condition.
- the accommodation facility reservation server 1 searches for accommodation facilities corresponding to all keywords included in the new accommodation facility search condition.
- the search condition 2 is integrated into the area search condition.
- the area search condition is “mountain diving, fireworks, all-you-can-drink”.
- the accommodation facility reservation server 1 searches for a region that matches all the keywords included in the new region search condition. Then, the accommodation facility reservation server 1 extracts a combination of the accommodation facility and the region that are related to each other from the newly searched accommodation facility and the region.
- the accommodation facility reservation server 1 determines whether or not the number of accommodation facilities searched using the new accommodation facility search condition is equal to or greater than the threshold value, and sets the search condition 2 to the region only when it is equal to or greater than the threshold value. Include in search criteria. The reason for making this determination is the same as the reason for making the determination using T2.
- the threshold value at this time is T3.
- the accommodation facility reservation server 1 sets the search condition 2 as a new accommodation facility search condition.
- the accommodation facility reservation server 1 integrates the search condition 1 into the region search condition when the number of accommodation facilities searched using the new accommodation facility search condition is T3 or more.
- the processing content when the number of found accommodation facilities is less than T3 is arbitrary.
- the accommodation facility reservation server 1 may transmit a search result page indicating that there is no corresponding accommodation facility to the user terminal 3.
- the accommodation facility reservation server 1 determines the area to be searched when the number of areas searched using the area search condition is less than the threshold value. Change to a larger area than the area that was previously searched. Then, the accommodation facility reservation server 1 searches for a region that matches all the keywords included in the region search condition from a plurality of regions that are newly searched. The reason for changing the region is that the wider the region, the more spots. Therefore, the wider the region, the higher the probability that it matches all the keywords included in the region search condition. In addition, the reason for performing the determination using the threshold is that when the number of searched areas decreases, the probability that a combination of accommodation facilities and areas that are related to each other is extracted from the searched accommodation facilities and areas is low. Because it becomes.
- the threshold used at this time is T4. T4 is an example of the third number in the present invention.
- a set of areas to be searched is defined by hierarchy.
- the set of areas in the first hierarchy is a set of municipalities.
- the set of regions in the second hierarchy is a set of regions formed by integrating a plurality of municipalities. Each region in this case is narrower than the prefecture.
- a set of regions in the third hierarchy is a set of prefectures. The lower the hierarchy number, the lower the hierarchy. In addition, the smaller the hierarchy number, the smaller the area of one region. Note that the number of hierarchies is arbitrary. In addition, it is also arbitrary how to define a set of regions based on what criteria in each layer.
- the accommodation facility reservation server 1 extracts the combination of an accommodation facility and an area using the search result at the time, when the number of areas more than T4 are searched. Note that the processing content in the case where only a region less than T4 is searched even if a search is performed on the uppermost region set is arbitrary. For example, the accommodation facility reservation server 1 may transmit a search result page indicating that there is no corresponding accommodation facility to the user terminal 3.

Then, it is assumed that the user desires the personal computer that it is manufactured by Company X, the office software is preinstalled, and the memory capacity is 4 GB. Accordingly, for example, as shown in FIG. 10A, the user designates “Company X personal computer office memory 4 GB” as a plurality of keywords.
- the online shopping mall server 4 searches for products corresponding to all of the plurality of specified keywords, and if the number of searched products is less than the threshold, the keywords are searched for the partial search condition 1 and the partial search. Split into condition 2.
- the threshold used at this time is T6.
- T6 is an example of the first number in the present invention.
- the criteria for dividing the plurality of keywords are arbitrary. For example, when M keywords are designated, the online shopping mall server 4 determines that the M keywords are partial search condition 1 including M ⁇ 1 keywords, partial search condition 2 including one keyword, You may divide into. The reason for dividing in this way is to make at least one product out of the products included in the combination to be extracted into a product that largely satisfies the user's request.
- the product searched using the partial search condition 1 is a product that largely satisfies the user's request.
- the online shopping mall server 4 obtains the number of products searched for by each of the M keywords, and puts the keyword having the smallest number of products searched into the partial search condition 2. Also good. This is because there is a probability that the keyword with the smallest number of products to be searched is the greatest factor that the user cannot obtain a sufficient number of search results desired by the user. By removing from the partial search condition 1 keywords that are a factor that the user cannot obtain a sufficient number of search results, the probability that a product that satisfies the partial search condition 1 can be searched can be increased. Note that the online shopping mall server 4 may divide a plurality of keywords by another method.
- products A-1, A-2, and A-3 are searched for as products that match "Company X Personal Computer Office".
- Product A-1 is a stationary personal computer.
- A-2 and A-3 are notebook personal computers.
- the products A-1, A-2, and A-3 are personal computers manufactured by Company X, and there is a possibility that office software is preinstalled.
- products B-1, B-2, and B-3 are retrieved as products that match the “memory 4 GB”.
- Product B-1 is a stationary personal computer.
- Product B-2 is an additional memory for a stationary personal computer.
- Product B-3 is a portable memory card.
- the products B-1, B-2, and B-3 are likely to have a memory capacity of 4 GB.
- the product A-1 and the product B-2 are in a relationship between the main product and the optional product. Therefore, a combination of the product A-1 and the product B-2 is extracted as a search result. This is because by incorporating the product B-2 into the product A-1, a personal computer that satisfies the user's request is completed. On the other hand, the product A-1 and the product B-1 have the same genre. However, the product A-1 and the product B-1 cannot be combined. Even if the product A-1 and the product B-1 can be used simultaneously, the product does not satisfy the user's request. Therefore, the combination of the product A-1 and the product B-1 is not extracted.
- the product B-2 cannot be incorporated into the product A-2 or the product A-3. Therefore, the combination of the product A-2 and the product B-2 and the combination of the product A-3 and the product B-2 are not extracted. Further, although the product B-3 may be connected to the products A-1 to A-3, the product B-3 is not an optional product for a personal computer. Therefore, the combination including the product B-3 is not extracted.
- Which combination of products is a combination of products related to each other may be changed according to the genre of the product, for example.
- a plurality of products having the same genre are not combinations of products related to each other.
- a plurality of products having the same genre may be a combination of products related to each other. For example, suppose a user wants to purchase a set of pots containing oysters, salmon and shrimp. Therefore, it is assumed that the user designates “nabe set oyster ⁇ shrimp” as a plurality of keywords.
- “Nabe Set Oyster Shrimp” is divided into, for example, “Nabe Set Oyster Shrimp” and “Shrimp”. Assume that a set of pots containing oysters and oysters is searched for as a product corresponding to “nabe set oyster bowl”, and an edible shrimp is searched as a product corresponding to “shrimp”. By putting shrimp in a pot containing oysters and crabs, the user can make a pot that he wants to eat. Both the pan set and shrimp are food.
- the online shopping mall server 4 can extract a combination of products that satisfy the user's request by extracting a plurality of products whose genre is food as a combination.
- the online shopping mall server 4 may further divide the partial search condition 1 into the partial search condition 1a and the partial search condition 1b when the number of products searched using the partial search condition 1 is less than the threshold value.
- the partial search condition 1a and the partial search condition 1b are examples of grandchild search conditions in the present invention.
- the online shopping mall server 4 stores products that match all the keywords included in the partial search condition 1a, products that match all the keywords included in the partial search condition 1b, and all keywords included in the search condition 2. Search for products that match.
- the online shopping mall server 4 uses any of the products searched using the partial search condition 1a, any of the products searched using the partial search condition 1b, and the product searched using the partial search condition 2.
- a combination of products related to each other may be extracted from the combination of any of the above.
- the threshold used at this time is T7. T7 is an example of the second number in the present invention.
- FIG. 10B is a diagram illustrating a division example of the partial search condition 1.
- “Company X personal computer office” is divided into partial search condition 1 including “X company personal computer” and partial search condition 2 including “office”.
- a personal computer manufactured by X company is searched for as a product matching “Company X personal computer”
- office software is searched as a product matching “Office”
- a personal computer is selected as a product matching “Memory 4 GB”.
- an additional memory for a computer is searched.
- the office software can be installed in the personal computer, the office software can be considered as an optional product of the personal computer.
- the additional memory is an optional product for personal computers. Therefore, a combination of personal computer, office software, and additional memory is extracted.
- the online shopping mall server 4 may divide a plurality of keywords initially specified by the user as search conditions into three or more partial search conditions. Also in this case, the online shopping mall server 4 searches for products for each partial search condition. The number of products included in the extracted combination is the same as the number of partial search conditions. The online shopping mall server 4 may also divide the partial search condition into three or more partial search conditions when further dividing the partial search condition.

- the online shopping mall server 4 may be composed of a plurality of server devices.
- FIG. 14 is a flowchart showing a processing example in the search processing of the system control unit 44 of the online shopping mall server 4 according to the present embodiment.
- the user operates the user terminal 6 to specify one or more keywords. Then, the user terminal 6 transmits a search request to the online shopping mall server 4.
- the search request includes the specified keyword.
- the search process is started when the online shopping mall server 4 receives a search request.
- the system control unit 44 acquires all the specified keywords from the received search request (step S81). Next, the system control unit 44 searches for products corresponding to all the specified keywords (step S82). Specifically, the system control unit 44 searches for product information including the specified keyword in at least one of the product name and the product description from the product information registered in the product information DB 42d. When a plurality of keywords are specified, the system control unit 44 searches for product information including all the keywords in at least one of the product name and the product description.
- step S83 the system control unit 44 determines whether or not the number of searched products is T6 or more (step S83). At this time, if the system control unit 44 determines that the number of searched products is equal to or greater than T6 (step S83: YES), the system search unit 44 displays a product search result page displaying a list of searched products as a search request. Is transmitted to the user terminal 6 that is the transmission source (step S84). After completing this process, the system control unit 44 ends the search process.
- system control unit 44 searches when one or more products that match all of the plurality of keywords specified by the user are searched when T6 is set to a value of 2 or more.
- a product search result page that displays a list of products that have been displayed may be transmitted to the user terminal 6.
- step S83 determines whether there are a plurality of designated keywords. At this time, if the system control unit 44 determines that there is only one designated keyword (step S85: NO), the product search result page displaying that there is no corresponding product is transmitted to the search request. It transmits to the original user terminal 6 (step S97). After completing this process, the system control unit 44 ends the search process.
- the system control unit 44 uses the specified keywords as the partial search condition 1 and the partial search condition 2 as a dividing unit. (Step S86). Specifically, the system control unit 44 acquires the number of products searched for with each of a plurality of designated keywords. At this time, the system control unit 44 may actually search for a product. The system control unit 44 may periodically search for products using various keywords, and store the number of searched products in the storage unit 42 in association with the keywords. Then, the system control unit 44 may acquire the number of products searched from the storage unit 42. The system control unit 44 includes one of the keywords having the smallest number of searched products in the partial search condition 2 and includes the remaining keywords in the partial search condition 1.
- step S87 the system control unit 44 searches for a product that matches all the keywords included in the partial search condition 1 as a search means (step S87).
- the search method in this case is basically the same as the search method in step S82.
- step S88 the system control unit 44 determines whether or not the number of searched products is T7 or more.
- step S88: NO the system control unit 44 determines whether the partial search condition 1 can be further divided (step S88: NO). Step S89). For example, it may be determined that division is possible until the number of keywords included in the partial search condition 1 reaches a preset number.
- the maximum number of divisions may be set in advance, and it may be determined that division is possible until the number of divisions is reached.
- the system control unit 44 determines that further division is possible (step S89: YES)
- the partial search condition 1 is divided into the partial search condition 1a and the partial search condition 1b as a dividing unit (step S90).
- the system control unit 44 includes, in the partial search condition 1b, one keyword that has the smallest number of products to be searched among the keywords included in the partial search condition 1 and includes the remaining keywords in the partial search condition 1a.
- the system control unit 44 sets the partial search condition 1a as the latest partial search condition 1 (step S91).
- the system control unit 44 proceeds to step S87 and searches for products corresponding to all the keywords included in the latest partial search condition 1.
- the system control unit 44 repeats the processes in steps S87 to S91 to search for and search using the partial search condition 1 until the number of products equal to or greater than T7 is searched or cannot be divided. Repeat the division of condition 1.
- step S89 when the system control unit 44 determines that the partial search condition 1 cannot be further divided (step S89: NO), the system control unit 44 proceeds to step S97.
- the system control unit 44 may search again for a plurality of keywords and proceed to step S87.
- the system control unit 44 divides the plurality of keywords by a method different from the division method in step S86. For example, the system control unit 44 may divide a plurality of keywords into a partial search condition 2 including two keywords and a partial search condition 1 including the remaining keywords.
- step S88 if the system control unit 44 determines that the number of searched products is equal to or greater than T7 (step S88: YES), it matches all keywords included in the partial search condition 2 as a search means.
- the product to be searched is searched (step S92).
- the search method in this case is basically the same as the search method in step S82.
- the system control unit 44 determines whether or not there is a partial search condition 1b (step S93). At this time, if the system control unit 44 determines that there is the partial search condition 1b (step S93: YES), as a search means, for each partial search condition 1b, all keywords included in the partial search condition 1b are included.
- the corresponding product is searched (step S94).
- the search method in this case is basically the same as the search method in step S82.
- step S93 When it is determined that there is no partial search condition 1b (step S93: NO), or when the process of step S94 is completed, the system control unit 44 uses the partial search condition 1 as an extraction unit. A combination of mutually related products is extracted from a combination of any product included in the corresponding product set and any product included in the corresponding product set searched using the partial search condition 2 ( Step S95).
- the system control unit 44 performs a search using the partial search condition 1b
- the system control unit 44 selects any product included in the corresponding product set searched using the partial search condition 1 and the partial search condition 2 Products related to each other from a combination of any product included in the corresponding product set searched using and one of the products included in the corresponding product set searched using the partial search condition 1b Extract combinations.
- the system control unit 44 when extracting a plurality of products having the same genre, acquires the genre ID from the product information of each product. Then, the system control unit 44 may specify a plurality of products whose genre IDs match each other among the corresponding product sets. In this case, it is determined whether or not the genre is the same at the lowest level. The system control unit 44 may extract a plurality of products having the same genre at the higher level than the lowest level. This is because if it is determined whether or not the genres are the same at the lower level, the range of products belonging to the same genre may be narrowed.
- the system control unit 44 can acquire the genre ID of the genre at a higher level than the lowest level for each product. Further, for example, when a plurality of products whose sales outlet stores are identical to each other, the system control unit 44 acquires a store ID from the product information of each product. Then, the system control unit 44 identifies a plurality of products whose store IDs match each other among the corresponding product sets. Further, for example, when extracting a plurality of products having a relationship between the main product and the optional product, the system control unit 44 acquires a product code from the product information of each product. Then, the system control unit 44 identifies a plurality of products registered in association with each other's product code between the corresponding product sets in the related product information DB 42e.
- the system control unit 44 transmits the HTML document of the product search result page displaying a list of the extracted combinations to the user terminal 6 that is the source of the search request (step S96). Specifically, the system control unit 44 displays information for display in the product information display area 210 based on the product name, product image URL, product price, product ID, etc. included in the product information of each product included in the combination. Is generated. Next, the system control unit 44 generates an HTML document including data for display in the product information display area 210. Then, the system control unit 44 transmits the generated HTML document. After completing this process, the system control unit 44 ends the search process. The user terminal 6 displays a product search result page based on the HTML document received from the online shopping mall server 4 as shown in FIG. 11, for example.
- the system control unit 44 may generate the HTML document of the product search result page so that both the searched product information and the searched combination information are displayed.
- step S91 the system control unit 44 sets the partial search condition 1a as the latest partial search condition 1 and also integrates the partial search condition 1b into the partial search condition 2 generated by the division in step S86. Good.
- the system control unit 44 of the online shopping mall server 4 converts a plurality of keywords specified as search conditions into partial search conditions 1 and 2 each including at least one keyword. Divided and searched for a product that matches all of the keywords included in the partial search condition and a product that matches all of the keywords included in the partial search condition for each partial search condition. A combination of products having a predetermined relationship with each other is extracted from a combination of any of the products and any of the products searched by the partial search condition 2. Therefore, even if there is no satisfactory product that matches all of the plurality of keywords specified as the search conditions, a sufficient number of search results desired by the user can be obtained without changing the search conditions.
- the system control unit 44 searches for a product that matches all of the plurality of keywords specified as the search conditions, the plurality of keywords are divided when the number of searched products is less than T6. . Therefore, it is possible to obtain a search result that is more desirable for the user and to prevent unnecessary search processing from being executed.
- system control unit 44 includes, in the partial search condition 2, one keyword that has the smallest number of products to be searched from among a plurality of keywords specified as the search conditions, and includes keywords that are not included in the partial search condition 2. Include in search condition 1. Therefore, the partial search condition 1 can be made as close as possible to the designated search condition, and the probability that a product can be searched by the partial search condition 1 can be increased.
- the present invention is applied when searching for an accommodation facility or a product as a search target.
- the present invention may be applied to, for example, searching for facilities other than accommodation facilities, places, services, web pages, images, videos, sounds, maps, news, blogs, and the like.
- the search device according to the present invention is applied to a server device in a client server system. That is, the terminal device transmits a keyword specified by the user to the server device, and the server device performs a search using the received keyword.
- the present invention may be applied to a stand-alone. In other words, the search device according to the present invention may directly accept specification of a keyword by the user, perform a search using the received keyword, display the search result, and provide the combination information directly to the user.
