The present invention can significantly improve the speed of a search operation by providing a user with a search result page created by a previous search operation in response to a query, when the non-popular query word is inputted, thereby avoiding the conventional method of having to create a new search result page. The present invention relates to a search result providing method and a search result providing system.

Search engines that support the search service typically prepare search results (search result pages) for popular queries such as events / persons that are recently fired and keywords with high input frequency, and receive the popular queries immediately after the user receives them. A method of providing a search result to a user who inputs the query word is adopted. In the search engine providing method, it is possible to optimally manage system resources by repeatedly providing a pre-written search result page instead of creating a new search result each time a query is input from the search engine side. The advantage is that you get the results quickly.

However, in the case of a non-popular query that does not pre-populate the search result page due to the low frequency of input, the search engine creates a new search result page from the point of time when the query is input, for example, searching and searching the DB for search information related to the input query. It is necessary to perform a series of processes, such as selecting the search information to be included in the search result page from the search results and creating a search result page using the selected search information. Accordingly, the speed of the search operation according to the input of the non-popular query is inevitably slowed.

Therefore, by actively utilizing the search result pages created by the previous search operation, especially the search result pages created according to the input of the non-popular query, a new type of search result can be maintained even if the non-popular query is input. The appearance of the model is urgently required.

The present invention has been made to solve the above problems, by providing a previously created search results page to the user to provide a search result providing method and a search result guaranteeing a high work speed even when receiving a low-frequency query It is an object to provide a system.

The present invention also provides a method and a search result providing method for determining a group for a user who has entered a query and performing an independent search operation on a search server related to the determined group, thereby improving search efficiency through distributed processing of the search request. The purpose is to provide a result delivery system.

In addition, the present invention records the search result page written in the storage space individually associated with the search server that performed the search operation, and if a similar query is input later, the search result page recorded in the storage space without creating a new search result page It is an object of the present invention to provide a search result providing method and a search result providing system that can be provided to the user by extracting the.

According to an aspect of the present invention, there is provided a method of providing a search result, the method comprising: maintaining a storage space in each search server to which a group identifier is individually assigned, determining a group of query words received from a user terminal, and determining In a search server of a group identifier associated with a group, searching for at least one search information corresponding to the query word in a predetermined database, and providing a search result page created using the search information to the user terminal; And recording, by the search server, the search result page in the storage space corresponding to the query word.

According to another embodiment of the present invention, a method for providing a search result includes maintaining storage space in each search server to which a group identifier is individually assigned, and determining a group of IP addresses utilized by a user terminal that inputs a query. And searching at a predetermined database for at least one search information corresponding to the query word in a search server of a group identifier related to the determined group, and searching a search result page created using the search information. And providing the search result page in the storage space in response to the query.

Hereinafter, a search result providing method and a search result providing system according to the present invention will be described with reference to the accompanying drawings.

Search result caching (SEARCH-RESULT CACHING) continuously used in the present specification is not limited to providing a user with a search result page written in response to a query, but by temporarily storing it in a cache which is a kind of storage means. It may mean a kind of search technique that actively uses the previously created search result page. Such search result caching enables the search engine to maintain a high search speed by utilizing previously generated search result pages even for non-popular query words with low input frequency.

The query word may mean a minimum amount of information that the user inputs into a search engine so that the user can search for content data to be viewed, answer data on questions in question, and the like through a search operation. Such a query word may be composed of one or more letters, words, and the like having semantic discrimination power. That is, the query word refers to a search keyword that a user who accesses a search engine for a search operation inputs into the search engine, and may include a plurality of words such as 'restaurant with the best night view'.

In addition, a search result page generated by a search server in response to a query word is provided to the corresponding user, including content data directly or indirectly related to the query word, and answer data for solving a problem that a user has a question about. Is the search result. The search server searches various data related to the user's query word received through a search engine in a predetermined database, and creates a search result page by arranging the searched various data according to a predetermined criterion. The created search result page is provided to the user by a search server or a search engine, and the user can acquire desired data or solve the current question through the provided search result page.

1 is a view for explaining a brief configuration of a search result providing system of the present invention.

The search result providing system 100 determines a group for the user 150 who has made a search request through a query input by the user 150 or an IP address utilized by the user terminal 155 inputting the query. In this case, the search operation may be performed in the specific search server 120 identified by the determined group. In addition, the search result providing system 100 performs a search result caching to store a search result page created as a result of a search operation in a storage space 130 that is individually associated with the corresponding search server 120. When inputting a query of 150, a environment for quickly extracting a search result page from the storage space 130 is provided.

First, the search engine 110 extracts the information about the data provider 160 that holds the content material that the user 150 wants to find from the predetermined database 140, and the user 150 to the extracted data provider 160. It may mean a search program or a search web server that supports a search operation to facilitate access. In addition, the search engine 110 may solve the questions of the user 150 by searching the database 140 to provide the user 150 with the answer data that may be optimal for the query input from the user 150. do.

The search engine 110 may include a plurality of search servers 120 to which a predetermined group identifier is individually assigned and actually performs a search operation. By the search operation of the plurality of search servers 120, the search engine 110 may distribute and process the search request of the user 150, thereby improving the search speed and maintaining the efficiency of the search operation at the same time. .

That is, the search engine 110 uses the plurality of search servers 120 to provide brief information on the data provider 160 that can provide the data requested by the user 150, and direct answer data for the query. By searching the database 140 and providing the user 150 with a search result page created using the searched data, the user 150 serves to maximize the search convenience.

The short information may include link information for accessing the data provider 160. When the user 150 clicks on the short information in the provided search result page with a command input tool (eg, a mouse), a search engine ( 110 may connect and connect the user 150 to a website operated by the data provider 160 using the link information.

The user 150 has a user terminal 155 for accessing the search engine 110, and sends a search request to the search engine 110 for the content information to be searched or for answering information on an issue with a question. An Internet user may be generated by inputting a query.

The user terminal 155 maintains a connection state with the search engine 110 through a communication network 170 such as the Internet, and searches in response to a query input by the user 150 to the connected search engine 110. It is a device that visualizes the search result page transmitted from the engine 110 or the search server 120 and provides it to the user 150.

The data provider 160 refers to a content provider (CP) that operates a website whose location on the network is designated by a predetermined network address, and provides the user 150 who accesses the website with brief information corresponding to the query word. Provide content materials. In addition, the data provider 160 may serve as an answerer who may provide, for example, question resolution information (answer data) on an issue for which the user 150 has questions.

The search result providing system 100 determines a user 150 who inputs a query as a predetermined group, induces distribution of the search operation through a search operation on a specific search server 120 identified in relation to the determined group. It is a device for improving the search efficiency. In particular, the search result providing system 100 performs a search result caching for recording the search result page generated by the previous search job in the storage space 130 associated with the search server 120 that performed the search job. The search result page may be quickly extracted from the storage space 130 for the similar query input of another user (or the same user) determined and provided to the user 150.

Hereinafter, a detailed configuration of a search result providing system of the present invention will be described with reference to FIG. 2.

2 is a block diagram showing a search result providing system according to an embodiment of the present invention.

The search result providing system 200 of the present invention may include a search server 120, a storage space 130, a group determining means 210, and a server identification means 220 associated with the search engine 110. .

First, the search server 120 performs a substantial search operation on a query input by a user 150 accessing the search engine 110 and may be distinguished by an individually assigned group identifier. The group identifier designates a unit group for classifying a specific query word or an IP address utilized by the user terminal 155 and performs a search operation in response to a query input (search request) of a specific user 150. Serves to identify 120. That is, the group identifier designates a unit group for classifying a predetermined character, or designates a unit group classified according to an IP address used by the user terminal 155 for a search operation.

For example, the group identifier 'group 1' assigned to the first search server may designate a unit group 11 in which the letters 'a, b, and c' are classified, and the user 150 having the letters a, b, and c as the first character. When the query is inputted, the search result providing system 200 of the present invention can identify the first search server to which the group identifier 'group 1' is assigned as a search server to perform a search operation.

Further, the group identifier 'Group 2' assigned to the second search server is the IP address '220.' 110. 66 'can be specified in the group group 22, the IP address of the class C utilized by the user terminal 155 inputting the query is' 220. 110. 66 'match, the search result providing system 200 of the present invention can identify the second search server to which the group identifier' group 2 'is assigned as a search server to perform a search operation.

The group determining means 210 determines a group of query words received from the user terminal 155 or a group of IP addresses utilized by the user terminal 155. That is, the group determining means 210 determines the group to which the user 150 who inputs the query belongs, and classifies by matching the characters constituting the query or the address indication number of the IP address related to the query input. The group of the user 150 may be determined by identifying the unit group.

In determining the group for the query, the group determining unit 210 may determine the group of the query by identifying a unit group that classifies a specific character among the characters constituting the query input by the user 150. For example, when the query word of the user 150 is 'the most expensive gem', the group determining unit 210 checks the first letter of the query word as 'a', and includes a unit including the identified 'a'. Group 11 can be identified. That is, the group determining means 210 may determine the group of the query word 'most expensive gemstone' as the identified unit group 11.

Further, in determining the group for the IP address, the group determining means 210 determines the group of the IP address by identifying a unit group for classifying the number of address indications of the IP address utilized by the user terminal 155 for query input. Can be. For example, the IP address of class C utilized by the user terminal 155 is' 220. 110. 66 ', the group determining means 210 determines the IP address' 220. 110. It is possible to identify unit group 22 that matches 66 '. That is, the group determining means 210 may determine the group of the IP address as the identified unit group 22.

The server identification means 220 identifies the search server 120 to which the group identifier associated with the determined group is assigned. That is, the server identifying means 220 confirms the group identifier designating the unit group relating to the query word identified in the group determining means 210 or the unit group relating to the IP address, and the search to which the identified group identifier is assigned. It identifies the server 120 from a plurality of search servers.

In the group determination for the query word, in the above example of identifying the unit group 11, the server identifying means 220 may identify the first search server to which the group identifier 'group 1' designating the unit group 11 is assigned. .

Further, in the above-described example of identifying the unit group 21 in the group determination for the IP address, the server identifying means 220 identifies the second search server to which the group identifier 'group 2' designating the unit group 22 is assigned. can do.

The search server 120 identified by the server identification means 220 performs a search operation in response to a query input by the user 150. The identified search server 120 searches the database 140 for at least one search information corresponding to the query word, and creates a search result page for arranging the search information based on a predetermined criterion. Here, the database 140 is a means for recording and maintaining the brief information about the data provider 160 and the answer information of the question in correspondence with the query word.

Thereafter, the search server 120 provides the created search result page to the user terminal 155 that inputs the query word through the communication network 170 and at the same time, the storage space 130 individually associated with the corresponding search server 120. The search result caching is performed to record and maintain the search result page in correspondence with the query word.

The storage space 130 may exemplify, for example, a cache, which is a physical and logical recording means for recording a search result page generated by the identified search server 120 corresponding to a query. That is, the storage space 130 corresponds to a query result that the previously created search result page is prepared in response to the same / similar query being input by a user (a user who has previously entered a query or a user who does not have a history). Play a role.

According to the record of the search result page to the storage space 130, that is, the search result caching, the search result providing system 200 of the present invention can significantly improve the search operation speed by making the most of the pre-written search result page. . In particular, when the search result providing system 200 inputs a query word having a low frequency of input, the search result providing system 200 provides a user with the created search result page, instead of providing the user 150 with the conventional method. It can be stored for a certain period of time at 130 to provide an environment for providing the user 150 with the search result page of the storage space 130 corresponding to the query without creating a new search result page every time the query is input. . For example, when a specific user 150 previously inputs a query, which is a history previously input, to generate a search request, the search result page is previously extracted from the storage space 130 in response to the query, and the user 150 is extracted. ) Can be provided.

When the search request is received from the second user terminal connected to the search engine 110 while the search result page created through the search operation is recorded in the storage space 130, the search result providing system 200 according to the present invention. ) May determine the user of the second user terminal as a predetermined group by using the information related to the received search request and perform a search operation on the search request in the search server 120 related to the determined group. The second user terminal may be a user terminal 155 of a user 150 having a history of previously inputting the same query word, or may be a user terminal 155 of a user 150 having no history.

That is, the server identifying means 220 may identify the search server 120 in relation to the query received from the second user terminal or the IP address utilized by the second user terminal.

In addition, the identified search server 120 extracts a search result page corresponding to the query from the storage space 130 in response to the query received from the second user terminal, and extracts the extracted search result page from the second user. It is provided to the user 150 of the terminal.

Accordingly, the search result providing system 200 continuously utilizes the previously created search result page to provide the user 150 with the previously created search result page without creating a new search result page for the search request from the second user terminal. To complete the search.

In addition, the search result providing system 200 creates a new search result page when a search result page corresponding to the query word is not recorded in the storage space 130 for the search request from the second user terminal. That is, a process of creating a search result page by searching and arranging various search information corresponding to the query word from the database 140 may be performed. The absence of a search result page corresponding to a specific query in the storage space 130 means that the search result page has not been created because there has been no search operation related to the query in advance, or the search result page is satisfied by satisfying a predetermined condition. This may mean removing the space 130. The above conditions can be set flexibly by the operator of the present system. For example, the condition can be set to the elapsed period when the search result page is recorded in the storage space 130, the allowable capacity of the storage space 130, and the like.

Hereinafter, referring to FIGS. 3 and 4, a search server 120 to perform a search operation according to a group of users 150 is determined, and a search result page previously prepared by search result caching is provided to the user 150. Explain what to do.

3 is a view for explaining an example of a search server to which a group identifier is individually assigned according to the present invention.

As described above, the search engine 110 may include a plurality of search servers 120 to which group identifiers are respectively assigned, and may allow the search requests of the user 150 to be distributed in the plurality of search servers 120. . At this time, the group identifier serves to identify the search server 120 that will actually perform the search operation for the search request of the specific user 150.

In FIG. 3, four search servers 120 to which group identifiers 'Group 1' to 'Group 4' are individually assigned associate storage spaces 130, respectively. The group identifier designates a unit group for classifying a predetermined number of characters constituting a query word, or designates a unit group classified according to the address indication number of the IP address utilized by the user terminal 155. The group identifier in FIG. 3 exemplarily designates unit groups related to the query and the IP address.

In FIG. 3, the group identifier 'Group 1' classifies the letters 'a, b, c' into unit group 11 and the IP address '220' of the class C utilized by the user terminal 155. Suppose that the group of units 21 classifying 110. 56 'is specified at the same time. Accordingly, the query word beginning with a or b or c from the user 150 is the IP address' 220. When input through the user terminal 155 utilizing 110. 56 ', the search result providing system 200 identifies the unit group 11 and the unit group 21, and simultaneously designates the identified unit group 11 and the unit group 21. The group identifier 'group 1' can be identified.

Similarly, in FIG. 3, the group identifier 'Group 4' classifies the letters 'T', ',', ',', '' and the unit group 14, and the IP address '220' of the class C utilized by the user terminal 155. Suppose that the group of units 24, classifying 110. 86 'is specified at the same time. Accordingly, in the future, the user's 150 query word starting with any one of the above-mentioned words is IP address' 220. When input through the user terminal 155 utilizing 110. 86 ', the search result providing system 200 identifies the unit group 14 and the unit group 24, and simultaneously designates the identified unit group 14 and the unit group 24. Check the group identifier 'Group 4'.

When a search request is received from the user terminal 155 under such an environment, the search result providing system 200 determines a group for the query word or an IP address utilized by the user terminal 155 of the user 150.

FIG. 4 is a diagram for explaining an example of recording a query word and a search result page generated in response to a query word in a storage space.

In FIG. 4B), the user 150 connected to the search engine 110 selects the most popular query word 'restaurant with the best night view' and the IP address '220.' 110. An example of input through the user terminal 155 utilizing 76 'is illustrated. According to a query input to the search engine 110, the search engine 110 determines whether the input query is related to a popular word, and in the case of a popular query, the search engine 110 extracts a search result page prepared in advance by the user ( 150). However, as shown in (i) of FIG. 4, when the inputted query is determined to be a non-popular term, the search result providing system 200 determines a group for the user 150 who inputs the query, and searches a server related to the determined group ( 120).

That is, in (i) of FIG. 4, the search result providing system 200 identifies a unit group 13 that classifies the first letter 'o' of the query word 'the best restaurant with the night view' and inputs the query word. ) Utilized IP address' 220. 110. Identify unit group 23, classified 76 '. In addition, the search result providing system 200 searches for a third search server to which the group identifier 'Group 3', which designates the unit group 13 and the unit group 23, is identified in response to the query 'restaurant with the best night view'. The search server 120 performs the operation.

Thereafter, the third search server searches for search information corresponding to the query word in the database 140, creates a search result page, and provides the created search result page to the user 150 through the user terminal 155. In FIG. 4), the user 150 provides a search result page in which search information such as knowledge iN, blog, etc. searched from the database 140 is arranged in accordance with a selected criterion in response to the query 'the best restaurant at night view'. Illustrates that.

In addition, the search result providing system 200 performs search result caching to record the created search result page in the storage space 130 corresponding to the query word, thereby preparing for inputting the same / similar query word later. In ii) of FIG. 4, the search result page generated by the third search server performing the search in response to the query 'best restaurant at night view' is recorded as a third storage space individually associated with the third search server. Doing. The search result page recorded in the third storage space can record the page itself in HTML format as in ii) of FIG. 4, and in another embodiment, the location on the network that actually holds the search result page, document identification information. Or the like.

Subsequently, when a group of any user 150 who inputs a query is determined and the determined group is related to the group identifier '3 group', the search result providing system 200 determines that the search operation for the query is group identifier '3'. Third group search server. This allows a specific search server 120 to perform a search operation exclusively for input of a low frequency input of a low frequency query, so that a large number of search result pages for a similar type of query word are retained in the storage space 130. This is to improve the search speed.

For example, with respect to the user 150 who inputs the query term 'recommend night view good restaurant', the search result providing system 200 records a search result page regarding 'night view' in a large amount in the storage space 130. May be determined as the search server 120 to perform a search operation. Thereafter, the determined third search server extracts a search result page corresponding to the previously entered query word 'restaurant with the best night view' from the third storage space and provides the user 150 similar to the query term 'recommend the restaurant with good night view'. can do.

In addition, the search result providing system 200 recognizes that similar query words tend to be repeatedly input in a predetermined network group, and a search operation is performed on the same search server 120 for a query word input using an IP address of a specific class. This can be done. For example, IP address of class C '220. 110. When 76 'network group is utilized by the user terminals associated with the restaurant community, the search result providing system 200 is a class C IP address' 220. 110. The search operation for the query input through the user terminal 155 using 76 'may be performed by a third search server that records a search result page related to a restaurant in the storage space 130.

If the search result page related to the query 'Night night restaurant recommendation' cannot be extracted from the third storage space, the third search server refreshes the search result page through a search operation in response to the query 'Night view good restaurant recommendation'. In addition, the newly created search result page may be provided to the user 150, and the search result page written in the third storage space may be recorded in response to the query 'recommended night view restaurant'.

Accordingly, according to the present invention, the search efficiency is determined through the distributed processing for the search request by determining a group for the user 150 who inputs the query and allowing an independent search operation to be performed in the search server 120 associated with the determined group. Can increase the effect.

In addition, according to the present invention, the previously created search result page is recorded in the individual storage space 130 in the search server 123 which performed the search operation, and the search result page is not newly created when a similar query is input later. By extracting the search result page recorded in the storage space 130 and providing the search result page to the user 150, the search operation speed may be significantly improved.

Hereinafter, the workflow of the search result providing system according to an embodiment of the present invention will be described in detail.

5 is a flowchart illustrating a search result providing method according to an embodiment of the present invention in detail.

The search result providing method of the present invention may be performed by the search result providing system 200 described above.

First, the search result providing system 200 maintains the storage space 130 as each of the search server 120 to which the group identifier is individually assigned (S510). The step S510 is a process of allocating a group identifier for each of the search servers 120 to identify the search server 120 to perform a search operation according to a query input among the plurality of search servers 120. In addition, in operation S510, the search result providing system 200 associates the storage spaces 130 with each of the search servers 120 to prepare for the recording of a search result page created through a later search operation.

In addition, the search result providing system 200 determines a group of query words received from the user terminal 155 (S520). This step (S520) is a process of determining a group of users 120 who input a query using a query. For example, when the query word "restaurant with the best night view" is input by the user 150, the search result providing system 200 identifies the unit group 13 that classifies the word "O". The group of 150 may be determined as the unit group 13 (see FIGS. 3 and 4).

Next, the search result providing system 200 creates a search result page in the search server 120 of the group identifier associated with the determined group (S530). This step (S530) identifies the search server 120 to perform a search operation in response to the query input, and to create a search results page using the search information retrieved through the search operation on the identified search server 120 It is a process. That is, the search result providing system 200 identifies the search server 120 that has assigned the group identifier designating the determined group (unit group) as the search server 120 to perform the actual search operation, and identifies the identified search server ( In operation 120, at least one search information corresponding to the query is searched in the database 140. In addition, the search result providing system 200 may create a search result page by arranging searched search information on a page. In the above-described example, the search result providing system 200 identifies the third search server to which the group identifier 'group 3' designating the unit group 13 is assigned, and by the identified third search server, the query 'night view is most likely to be used. You can create a search results page in response to "a good restaurant."

In addition, the search result providing system 200 provides the created search result page to the user terminal 155, and records the search result page in the storage space 130 in correspondence with the query (S540). In operation S540, a search result page is provided to the user terminal 155 as a search result in response to the input query, and the storage space 130 associated with the search server 120 performing the search operation on the search result page. ) To prepare for similar query input later. The search result page recording to the storage space 130 may record the HTML page itself in correspondence with the query word, or may record the document ID regarding the storage location where the search result page is actually recorded in correspondence with the query word. .

Subsequently, the search result providing system 200 determines a group of query words received from the second user terminal (S550). In operation S550, a query is input by a user 150 who previously inputs a query or a new user 150, and a group of a user (second user) who inputs a query is determined. That is, the search result providing system 200 determines a group of query words by checking a unit group that classifies at least one letter included in the query word. For example, the search result providing system 200 may determine the unit group 13 as a group for the user 150 who inputs the query term 'night view restaurant recommendation' similar to the query word 'the restaurant having the best night view'. .

In addition, the search result providing system 200 extracts a search result page from the storage space 130 in response to the query in the search server 120 of the group identifier associated with the determined group (S560). In step S560, the user 150 who inputs a query similar to the previously input query is determined as the same group, and the search server 120 performs a search operation on the determined group without creating a new search result page. In this case, the previously created search result page is extracted to the storage space 130.

In addition, the search result providing system 200 in this step (S560) has not previously entered a similar query, so that the search result page is not recorded in the storage space 130, or the search result page is a storage space under a predetermined condition If it is erased at 130, a process of newly creating a search result page corresponding to the input query may be performed. That is, if the search result providing system 200 does not extract the search result page, the search result corresponding to the query word may be searched in the database 140 and the search result page may be created using the searched search information. As a condition for erasing the search result page, for example, the operator of the present system may (1) when a predetermined period has elapsed since the search result page is recorded in the storage space 130, and (2) to the storage space 130. It can be set when there is not enough free space to record the search result page. The setting of such an erasing condition is necessary to secure an area (capacity) of the storage space 130 to record the newly created search result page by sequentially deleting the old search result pages recorded in the storage space 130. .

Next, the search result providing system 200 provides the extracted search result page to the user terminal 155 (S570). This step (S570) is a process for recycling the previously created search result page to be provided as result information to the user 150. According to the extraction of the search result page from the storage space 130 and the provision of the user 150, the present invention can minimize the creation of a new search result page, and even in the case of inputting a non-popular query, the search result page Can take full advantage of this to significantly speed up the search process.

Therefore, according to the present invention, a previously created search result page can be provided to the user 150 as a search result, so that even when a query word with low input frequency is received, a search operation can be performed remarkably. .

As another embodiment of the present invention, it will be described to determine the group of the user 150 using the IP address utilized by the user terminal 155 inputting the query.

6 is a flowchart illustrating a search result providing method according to another exemplary embodiment of the present invention.

The search result providing system 200 maintains the storage space 130 as each of the search servers 120 to which the group identifiers are individually assigned (S610). In operation S610, a group identifier for identifying a search server 120 to perform a search operation according to a query input among a plurality of search servers 120 associated with the storage space 130 may be provided to the search server 120. An individual allocation process is similar to the above-described step S510.

In addition, the search result providing system 200 determines a group of IP addresses utilized by the user terminal 155 (S620). This step (S620) is a process of determining the group of the user 120 that input the query using the IP address of the user terminal 155. For example, the query 'the best restaurant at night view' is the class C IP address' 220. 110. When inputted through the user terminal 155 utilizing 76 ', the search result providing system 200 receives an IP address' 220. 110. By identifying the unit group 23 classifying 76 ', the group of the user 150 may be determined as the unit group 23 (see FIGS. 3 and 4).

Next, the search result providing system 200 creates a search result page in the search server 120 of the group identifier associated with the determined group (S630). This step (S630) identifies the search server 120 to perform a search operation in response to the query input, and to create a search results page using the search information retrieved through the search operation on the identified search server 120 As a process, it is similar to step S630 described above. In the above-described example, the search result providing system 200 identifies the third search server to which the group identifier 'group 3' designating the unit group 23 is assigned, and by the identified third search server, the query 'night view is most likely to be used. You can create a search results page in response to "a good restaurant."

In addition, the search result providing system 200 provides the created search result page to the user terminal 155, and records the search result page in the storage space 130 in correspondence with the query (S640). This step (S640) is a process of providing a search result page to the user terminal 155 in response to the input query, and processing the search result caching to record the search result page in the storage space 130 corresponding to the query. This is similar to step S640 described above.

Subsequently, the search result providing system 200 determines a group of IP addresses utilized by the second user terminal (S650). This step (S650) is a process of receiving a query by the user 150 or a new user 150 who previously entered the query, and determines a group for the user (second user) who entered the query, as described above Similar to step S650. For example, in the network group to which the user terminal 155 that previously entered the query belongs, IP address '220.' The search result providing system 200 may determine the unit group 23 as a group with respect to the user terminal 155 input by using a query similar to the above-described query "restaurant with the best night view" using 110. 76 '.

In addition, the search result providing system 200 extracts a search result page from the storage space 130 in response to the query in the search server 120 of the group identifier associated with the determined group (S660). This step (S660) takes into consideration that similar queries can be continuously input in the same network group, the user terminal 155 inputting the query using the previously used IP address into the same group as before. It's a decision process. In addition, the search result providing system 200 in operation S660 may store the previously created search result page in the storage server 130 without newly creating a search result page in the search server 120 performing a search operation on the determined group. Can be extracted.

In addition, the search result providing system 200 in this step (S660) is that the search result page is not recorded in the storage space 130 because there is no previous input of a similar query or the search result page in the storage space under a predetermined condition If it is deleted at 130, a process of newly creating a search result page corresponding to the input query may be performed. That is, if the search result providing system 200 does not extract the search result page, the search result corresponding to the query word may be searched in the database 140 and the search result page may be created using the searched search information. As a condition for erasing the search result page, for example, the operator of the present system may (1) when a predetermined period has elapsed since the search result page is recorded in the storage space 130, and (2) to the storage space 130. It can be set when there is not enough free space to record the search result page. The setting of such an erasing condition is necessary to secure an area (capacity) of the storage space 130 to record the newly created search result page by sequentially deleting the old search result pages recorded in the storage space 130. .

Next, the search result providing system 200 provides the extracted search result page to the user terminal 155 (S670). This step (S670) is a process for recycling the previously created search result page to be provided as the result information to the user 150.

Therefore, according to the present invention, new creation of a search result page can be minimized, and even when a non-popular query word is input, the search operation speed can be remarkably improved by making the most of the previously created search result page.
