Description

  The present invention relates to a search support program for providing an appropriate web page in a website to a user who has accessed the website.

  As is well known, a search engine (search engine) accepts a keyword from a user in order to directly access a web page having information desired by the user and information related thereto, and a web page including the keyword in the content. A URL [Uniform Resource Locator] is searched from a search database (index file) created in advance, and a list of link buttons in which the detected URLs are embedded is displayed.

  The above-described search database creation method is generally divided into two types: a directory type and a robot type. In the directory type, the title, URL, and content description of each web page are classified into categories by the manual operation of the search engine operator and registered in the search database. On the other hand, in the robot type, a crawler (also called a spider) collects source data of web pages on the Internet and source data of destination web pages jumped from links in each web page, and an indexer collects them. Search terms are extracted from the source data according to a predetermined rule, and the title, URL, and search term of each web page are associated with each other and registered in the search database.

  Each web page that constitutes a website is usually linked with a tree-type link structure so that the home page is the top page, and the website is displayed and navigated from the home page to the lower-level web page. It has been.

The crawler described above automatically crawls not only the home page of each website but also all the web pages in the website associated as a lower layer of the home page. As long as the web page satisfies the predetermined condition, it is registered in the search database regardless of whether it is a lower layer.
"SEO is a robot search engine countermeasure crawler and indexer", [online], Janic Corporation, [searched July 13, 2004], Internet <URL: http://www1.ttcn.ne.jp/~ kimiya / about_seo.html> “Search Engine (SEO) Countermeasures”, [online], last updated on June 1, 2004, Kimiya Watanabe, [searched on July 13, 2004], Internet <URL: http: // seo-robot .j-nic.co.jp / indexer.html> "Access improvement failure", [online], last updated on August 15, 2002, IGRO'S (searched on July 13, 2004), Internet <URL: http: //www.igros. tv / access_re3.html>

  By the way, in the above-described robot type search engine, the crawler often circulates each site on the Internet periodically or every day continuously in preparation for the search, but it is said to be 4 billion on the Internet. Since the web page exists, even if the content of any web page is updated, it may take several days to several weeks for the update to be reflected in the search database.

  However, since a search engine may have to perform a search using a search database that does not reflect web page updates, the link selected from the search results generated by the search engine. When the content of the previous web page is updated, the web page is detected based on the content before the update. Therefore, the web page contains information desired by the user. May not be included. When the information desired by the user is not included in the web page due to the update, the user is confused by seeing the web page.

  In particular, if the web page registered in the search database is a web page of another search site or a mail-order site, such a site has a fast obsolescence such as current information or new products. Search by search sites because there are many web pages that contain information (the more likely they are the lower layers in that type of site), and the content is likely to be updated frequently When the result jumps directly to a lower-level web page of a site such as another search site or a mail order site, the above-mentioned confusion easily occurs.

  Also, from the standpoint of the operator of a site such as a search site or a mail-order site, if it seems to confuse users who have accessed the site via the search results of another search site, Therefore, it is desired to provide a web page that is optimal for a user who has accessed the site through a search result of another search site.

  The present invention has been made in view of such problems, and the problem is that a user who has accessed the local site via a search result of another search site can obtain the optimal web for that user as much as possible. It is to be able to provide a page.

  A search support program invented in order to solve the above-described problem, a computer receives a HTTP request through a communication device, a web page indicated by a URL in a request line of an HTTP request received by the reception unit Response generation means for generating an HTTP response including data, reference source information acquisition means for acquiring the URL of the reference source page from the HTTP request received by the reception means, and the URL acquired by the reference source information acquisition means is the domain of the search site The keyword acquisition means for acquiring a keyword from the URL when the URL includes the URL, and the keyword from a storage device that stores the URL of the web page data on the network and the page content information related to the content of the web page data in association with each other. Acquisition means Extraction means for extracting the URL corresponding to the page content information including the acquired keyword, and the domain and path of the URL extracted by the extraction means are the URL domain and path in the request line of the HTTP request received by the reception means. Incorporation of information for displaying instruction means for executing search of the database for search by the keyword acquired by the keyword acquisition means and display of a list of the search results into the HTTP response when they match And a function of transmitting the HTTP response to the transmission source of the HTTP request through the communication means.

  When this search program is executed in a computer having a database in which the URL of a web page and page content information are stored in association with each other, when the reference source page is a search result list page when an HTTP request is received, A keyword is acquired from the URL of the reference source page, and information for displaying instruction means for executing a search using the keyword as a search condition and a list display of the search result together with the web page is incorporated in the HTTP response. And sent to the requester. Accordingly, the requesting computer that has transmitted the HTTP request displays the web page and the instruction unit based on the information incorporated in the HTTP response. Therefore, the user of the requesting computer, when the desired information is not included in the web page displayed via the search result of the search site, through the instruction means displayed together with the web page, Web pages that can be searched using the same keyword in the database of the computer, and the search result is a web page that lists a web page that the user desires and a link button for accessing such a web page. Can be displayed.

  In other words, even if some of the information stored in the search database used in the search site is old, even if there is no desired information in the destination web page from the search result of the search site Since the appropriate information can be acquired easily based on the search result at the jump destination site by the instruction means, the user is not confused.

  Therefore, according to the present invention, it is possible to provide the most suitable web page for a user who has accessed the site through the search result of another search site as much as possible.

  Hereinafter, based on an accompanying drawing, two forms for carrying out the present invention are explained.

Embodiment 1

  FIG. 1 is a schematic diagram of a computer network system according to the first embodiment of the present invention. The computer network system of the first embodiment includes a web server device 10 and a web client device 20, and at least a first web page search device 30 and a second web page search device 40. The devices 10 to 40 are connected to each other via a network N.

  The web server device 10 is a so-called general-purpose computer to which a function as a web server is added, and includes a CPU [Central Processing Unit], a RAM [Random Access Memory], a communication adapter, and a storage device. The storage device stores web page data 11 and a web server program 12 in addition to the operating system program.

  The web page data 11 is source data composed of text described in a hypertext markup language. Each web page data 11 is assigned a unique URL [Uniform Resource Locator]. The web page data 11 forms a website by being associated with each other.

  The web server program 12 is a program for adding a function as a web server to a general-purpose computer. More specifically, the web server program 12 receives web page data 11 or image data (not shown) in response to a request from the web client device 20. Send.

  The web client device 20 is a so-called personal computer to which a function as a web client is added, and includes a display device such as a liquid crystal display, an input device such as a keyboard and a mouse, and a main body connected to these devices. Yes. The main body incorporates a CPU, RAM, communication adapter, FDD [Flexible Disk Drive], CDD [Compact Disk Drive], and HDD [Hard Disk Drive]. The HDD is a web client in addition to an operating system program. A program 21 is stored.

  The web client program 21 is a program for adding a function as a web client (so-called web browser) to a personal computer. More specifically, the web client program 21 is a web indicated by a URL specified by an operator of the web client device 20. This is a program for requesting page data from the web server device 10 storing it, acquiring the requested web page data from the web server device 10 and displaying the web page on a display device.

  Each of the first web page search device 30 and the second web page search device 40 is a general-purpose computer to which a search engine function is added, and includes a CPU, a RAM, a communication adapter, and a storage device.

  In addition to the operating system program, the storage device of the first web page search device 30 stores web page data 31, a web server program 32, a search database 33, a robot program 34, and a search program 35.

  The web page data 31 is the same source data as the web page data 11 of the web server device 10, and a unique URL is assigned to each of them. Each web page data 31 is associated with a tree-type link structure so that the home page is a top page and is displayed (navigated) from the home page to a lower layer web page. At least web page data for displaying a home page displays a text box for inputting a keyword and a search execution button for instructing execution of a search using the keyword as a search condition. Features are built in. Thus, the web page data 31 constitutes a search site.

  The web server program 32 is a program that exhibits the same function as the web server program 12 of the web server device 10.

  The search database 33 is a database in which records are stored in which titles and URLs of the web page data 11 of the web server devices 10 and search terms extracted from the contents are associated with each other. The robot program 34 acquires the web page data 11 of the web server device 10 connected to the network N, extracts search terms from the acquired web page data 11 according to known rules, and stores the search terms in the search database 33. A program for adding or updating records. The robot program 34 is periodically executed by the CPU of the first web page search device 30.

  The search program 35 is a program for searching the search database 33. As the search condition, the keyword input in the text box when the search execution button on the homepage described above is clicked is used. When a CPU that performs a search according to the search program 35 detects a record that includes a keyword as a search term, a CPU displays a search result list page (see FIG. 2) that lists link buttons that include URLs included in the detected record. Web page data for display is generated.

  Similar to the first web page search device 30, the storage device of the second web page search device 40 includes an operating system program, web page data 41, a web server program 42, a search database 43, a robot program 44, and a search. The program 45 is stored. The web page data 41 constitutes a search site different from the first web page search device 30. The storage device further stores a guidance program 46 and a search support function addition program 47.

  The guidance program 46 provides a function by the search support function addition program 47 when the web client device 20 accessed through the search result list page (see FIG. 2) by the first web page search device 30 satisfies the conditions described later. It is a program for guiding to the URL to be performed. The search support function adding program 47 is a program for adding information that exhibits the search support function to the web page data transmitted to the accessing web client device 20. The contents of processing executed by the CPU of the second web page search device 40 in accordance with these programs 46 and 47 will be described later.

  Processing executed in the computer network system according to the first embodiment configured as described above and its operation will be described.

  First, the user of the web client device 20 starts the web client program 21 and specifies the URL of the web page data 31 for the home page of the first web page search device 30. Then, the web client device 20 transmits an HTTP request to the first web page search device 30 according to the web client program 21. In response to this HTTP request, the first web page search device 30 transmits an HTTP response including web page data 31 for the home page to the web client device 20 according to the web server program 32.

  When receiving the HTTP response including the web page data 31 for the home page, the web client device 20 displays the home page on the display device based on the web page data 31 according to the web client program 21. As mentioned above, this home page includes a text box and a search execution button, and the user enters a keyword that he / she thinks is necessary to extract a web page containing the desired information in the text box. When the search execution button is clicked, the web client device 20 transmits an HTTP request including these keywords to the first web page search device 30 according to the web client program 21.

  When receiving the HTTP request including these keywords, the first web page search device 30 searches the search database 33 for records including these keywords in the search term according to the search program 35, and the URL of the detected record Web page data for displaying a search result list page showing a list of link buttons embedded with is generated. Then, the first web page search device 30 transmits an HTTP response including the generated web page data to the web client device 20 according to the web server program 32.

  When receiving the HTTP response including the generated web page data, the web client device 20 displays a search result list page on the display device based on the web page data. FIG. 2 is a diagram illustrating an example of the search result list page 51. FIG. 2 shows a case where “Mike” and “basket shoes” are searched as keywords.

  Thereafter, the user of the web client device 20 jumps to one URL of the web page data 41 of the second web page search device 40 from the link buttons 51a, 51b,. The link button 51b is selected, and the selected link button 51b is clicked. Then, according to the web client program 21, the web client device 20 transmits an HTTP request including the URL embedded in the link button 51b to the second web page search device 40.

  When the second web page search device 40 receives this HTTP request through a communication adapter (not shown) corresponding to the receiving means or the web server program 42, the second web page search device 40 starts the guidance program 46 and starts the guidance process. FIG. 3 is a flowchart showing the contents of the guidance process. As shown in FIG. 3, the guidance process includes steps S101 to S109. Note that the second web page search device 40 (CPU) that executes steps S101, S103, S106, S107, and S109 corresponds to a reference source information acquisition unit, a keyword acquisition unit, and an extraction unit.

  In step S101, the second web page search device 40 (or its CPU) reads the referrer value included in the request header field of the received HTTP request. That is, the second web page search device 40 acquires the URL of the search result list page (reference source page) 51 that the web client device 20 displays on the display device at this time. The URL includes a scheme, a host, a port, a path, a parameter, and a query.

  In the next step S102, the second web page search device 40 refers to a table (not shown) created in advance, so that the domain included in the URL acquired in step S101 is that of the search site. It is determined whether or not. If the second web page search device 40 determines that the domain is not for the search site (S102; NO), it proceeds to step S108 and determines that the domain is for the search site ( (S102; YES), the process proceeds to step S103.

  In step S103, the second web page search device 40 acquires data added after “=” in the URL acquired in step S101, and decodes this data. As a result, the second web page search device 40 acquires the keywords used by the web client device 20 to acquire the search result list page 51 currently displayed on the display device.

  In the next step S104, the second web page search device 40 includes words registered in advance for the search site (for example, the name of the search site, company name, Alternatively, if there is a keyword that is the same as a word that is not suitable for a search such as “product” or “mail order”, it is excluded.

  In the next step S105, the second web page search device 40 cuts the keywords after the exclusion process in step S104 into words, and temporarily stores these words in the RAM as a first parameter group. At the same time, the first word among the divided words is temporarily stored in the RAM as the second parameter group.

  In the next step S106, the second web page search device 40 extracts a record having the optimum URL from the search database 43 based on each word cut out from the keyword in step S105. There are various methods for extracting records, and one example is the following method. That is, the second web page search device 40 repeatedly searches the database 43 for search while increasing the words to be adopted as search conditions from each word one by one from the top side. If there are detection times less than a predetermined number (for example, 4) of the detection numbers in each search condition, the record of that time is temporarily stored in the RAM, and if there are no detection times below, the detected record is detected. A predetermined upper number (for example, four) of the records is specified from the records in the detection time with the smallest number, and these records are temporarily stored in the RAM.

  In the next step S107, the second web page search device 40 uses the URL of any record in which the combination of the domain and path of the URL in the request line of the HTTP request received from the web client device 20 is extracted in step S106. It is determined whether or not the combination of the domain and path matches. When it is determined that the combination of URL domain and path in the request line of the HTTP request matches the combination of URL and path of any record (S107; YES), the second web page search device 40 Advances the process to step S108.

  In step S108, the second web page search device 40 generates an HTTP response including the web page data 41 indicated by the URL in the status line of the HTTP request received from the web client device 20 in the message body (entity body). The HTTP response is transmitted to the web client device 20 according to the web server program 42. After the transmission, the second web page search device 40 ends the guidance process.

  On the other hand, if it is determined in step S107 that the URL domain and path combination in the request line of the HTTP request does not match the URL domain and path combination of any record (S107; NO), 2 Web page search device 40 advances the process to step S109.

  In step S109, the second web page search device 40 reads the URL from the request line of the HTTP request received from the web client device 20, and specifies the search support function addition program 47 for the URL, and the reference source page. And the first parameter group and the second parameter group stored in the RAM in step S105 are added. Subsequently, the second web page search device 40 incorporates the URL to which the above-described information is added into the response header field of the HTTP response transmitted to the web client device 20 as a location value and “301” in the status line. Is transmitted as a status code, and this HTTP response is transmitted to the web client device 20 in accordance with the web server program 42. After the transmission, the second web page search device 40 ends the guidance process.

  By this guidance processing, when the web client device 20 jumps from the search result list page 51 to the web page of the second web page search device 40, the keyword used to display the search result list page 51 is the second keyword. When the condition set in the web page search device 40 is met (S107; YES), the requested web page data 41 is acquired through the HTTP request, and when the condition is not met (S107; NO). Is specified by the status code “301” and the location value of the HTTP response, the URL is redirected to the URL where the function of the search support function adding program 47 operates.

  When redirecting, the web client device 20 includes the URL included as a location value in the HTTP response in the request line of the HTTP request, and transmits the HTTP request to the second web page search device 40.

  Upon receiving this HTTP request, the second web page search device 40 starts the search support function addition program 47 based on the information specifying the search support function addition program 47 in the URL in the request line, and the search support function Start additional processing. FIG. 4 is a flowchart showing the contents of the search support function adding process. As shown in FIG. 4, the search support function adding process includes steps S201 to S203. The second web page search device 40 (or its CPU) that executes steps S201 to S203 corresponds to a response generation unit, an information incorporation unit, and a transmission unit.

  In step S201, the second web page search device 40 (the CPU thereof), the information specifying the search support function addition program 47 from the URL in the request line of the HTTP request received from the web client device 20, the search site name, The web page data 41 indicated by the remaining URL is acquired by excluding the first parameter group and the second parameter group.

  In the next step S202, the second web page search device 40 incorporates a script into the web page data 41 acquired in step S201. This script is for displaying a menu screen as an overlay on the web page when the web page is displayed based on the web page data 41. FIG. 5 is a diagram showing an example of the menu screen 52. As shown in FIG. 5, the search screen name 52a added to the URL is displayed on the menu screen 52, and the search program 45 is executed using the first parameter group added to the URL as a search condition. A link button 52b for executing and displaying the result list page, and a link button 52c for displaying the search result list page by executing the search program 45 using the second parameter group added to the URL as a search condition. ,It is shown. The menu screen 52 may have a function of being displayed at a certain position even when the web page is scrolled. As a script for displaying such a menu screen 52, for example, there is a “moveMenu” function in JAVA Script language (JAVA is a trademark of Sun Microsystems, Inc., USA).

  In the next step S203, the second web page search device 40 generates an HTTP response including the web page data 41 in which the script is incorporated in step S202 in the message body, and the web client device 20 uses this HTTP response according to the web server program 42. Send to. After the transmission, the second web page search device 40 ends the search support function addition process.

  The web client device 20 that has received the HTTP response by the search support function adding process displays a web page based on the web page data 41 included in the message body of the HTTP response on the display device according to the web client program 21. At this time, the web client device 20 displays the menu screen 52 as an overlay on the web page based on the script incorporated in the web page data 41. FIG. 6 is a diagram showing a state in which the menu screen 52 is displayed as an overlay on the web page 53. In FIG. 6, the web page 53 shows a list of search results by the second web page search device 40. This is because the web page 53 in the search result list page 51 shown in FIG. The link button for jumping to is generated because the information indicating the search execution instruction and the keyword that is the search condition are embedded in advance, and a guidance process and a search support function are added. It is not displayed as a search result list by processing.

  When the user of the web client device 20 sees the web page 53 on which the menu screen 52 is overlaid and the desired information is not described in the web page 53, the link buttons 52b and 52c on the menu screen 52 are displayed. Click one of these.

  Then, the web client device 20 transmits an HTTP request including the URL embedded in the clicked link button in the request line according to the web client program 21 to the second web page search device 40.

  When the second web page search device 40 receives the HTTP request, the second web page search device 40 starts the search program 45, and uses the first parameter group or the second parameter group included in the URL as a search condition for the search program 45. The search of the search database 43 is executed. Then, the second web page search device 40 generates web page data for displaying the search result list page indicating the search result as a link button, and includes the web page data in the message body according to the web server program 42. The response is transmitted to the web client device 20.

  When receiving the HTTP response, the web client device 20 displays a search result list page on the display device based on the web page data included in the message body of the HTTP response according to the web client program 21. FIG. 7 is a diagram showing an example of the search result list page 54. FIG. 7 shows a search result list page displayed when the link button 52b in which the URL to which the first parameter group is added is clicked out of the two link buttons 52b and 52c on the menu screen 52. .

  As described above, according to the computer network system of the first embodiment, when the second web page search device 40 receives an HTTP request and the reference source page is a search result list page, the reference source A keyword is acquired from the URL of the page, and a menu screen 52 including link buttons 52b and 52c for executing a search using the keyword as a search condition and a list display of the search result as an instruction means is displayed together with a web page. Is incorporated into an HTTP response and transmitted to the request source. As a result, the requesting web client device 20 that has transmitted the HTTP request displays the web page and the menu screen 52 based on the information incorporated in the HTTP response. For this reason, the user of the web client device 20 as the request source, when the desired information is not included in the web page 53 displayed via the search result of the search site, the link button on the menu screen 52 The search result using the same keyword in this search site can be displayed by 52b and 52c.

  That is, when a part of information stored in the search database 33 used in the search site (first web page search device 30) is old, the destination web is jumped from the search result of the search site. Even if there is no desired information on the page 53, the link buttons 52b and 52c can be used to easily select a desired web page from the web page displayed based on the search result on the jump destination site (second web page search device 40). Since information can be acquired, the user is not confused.

Modified example

  In the first embodiment described above, the menu screen 52 is displayed as an overlay on the web page 53, but is not limited thereto. As a modification of the first embodiment, the menu screen 52 is displayed in a window different from the window in which the web page 53 is displayed.

  Specifically, the second web page search device 40 has a menu screen 52 on which search site name 52a and link buttons 52b and 52c are displayed for the web page data in step S202 in the search support function addition process of FIG. A script for displaying in a window different from the web page 53 is incorporated. As a script for displaying the menu screen 52 in such another window, for example, there is a Menu_open function of JAVA Script language.

  Also according to the modified example of the first embodiment, the user can obtain a part of the information stored in the search database 33 used in the search site (first web page search device 40). Even if there is no desired information in the jumped web page 53 from the search result of the search site, the jump destination site (second page) can be easily accessed by the link buttons 52b and 52c in a separate window from the web page 53. Since desired information can be acquired from the web page displayed based on the search result in the web page search device 40), there is no need to be confused.

Embodiment 2

  FIG. 8 is a schematic diagram of a computer network system according to the second embodiment of the present invention. The computer network system of the second embodiment has almost the same configuration as the computer network system of the first embodiment. However, the difference is that some contents of the guidance program 46 are different, a page data transmission program 48 is installed in the second web page search device 40 instead of the search support function addition program 47, and The menu display program 22 is installed in each web client device 20.

  First, the content of the guidance process of the second embodiment is almost the same as steps S101 to S109 of the first embodiment. The difference is that the information incorporated in the URL by the second web page search device 40 in step S108 of FIG. 3 is not the information specifying the search support function addition program 47 but the information specifying the page data transmission program 48. ing. The second web page search device 40 (or its CPU) that executes step S108 corresponds to an information incorporation means.

  Next, the contents of the page data transmission process executed by the second web page search device 40 according to the page data transmission program 48 will be described. FIG. 9 is a flowchart showing the contents of the page data transmission process. As shown in FIG. 9, the page data transmission process includes steps S301 and S302. Note that the second web page search device 40 (or its CPU) that executes steps S301 and S302 corresponds to a response generation unit and a transmission unit.

  In step S301, the second web page search device 40 (or its CPU) specifies information specifying the page data transmission program 48 from the URL in the request line of the HTTP request received from the web client device 20, the search site name, Excluding the first parameter group and the second parameter group, the web page data 41 indicated by the remaining URL is acquired.

  In the next step S302, the second web page search device 40 generates an HTTP response including the web page data 41 acquired in step S301 in the message body, and transmits this HTTP response to the web client device 20 according to the web server program 42. To do. After the transmission, the second web page search device 40 ends the page data transmission process.

  The web client device 20 that has received the HTTP response by the page data transmission process displays a web page based on the web page data included in the message body of the HTTP response on the display device according to the web client program 21.

  The web client device 20 monitors the URL according to the tool program downloaded in advance from the second web page search device 40 as a tool function and a tool bar to be added to the function of the web client program 21. When the change is detected, the menu display program 22 which is an add-in program of this tool program is activated to start the menu display process. FIG. 10 is a flowchart showing the contents of the menu display process. As shown in FIG. 10, the menu display process includes steps S401 to S403.

  In step S401, the web client device 20 (the CPU thereof) stores a difference between the URL of the web page currently displayed on the display device at this time and the URL of the web page displayed on the display device immediately before, in the RAM. Memorize temporarily.

  In the next step S402, the web client device 20 stores the difference part stored in the RAM in step S401, the information specifying the page data transmission program 48, the search site name, and the first and second parameter groups. It is determined whether or not. When the web client device 20 determines that the difference is not information including the information specifying the page data transmission program 48, the search site name, and the first and second parameter groups (S402; NO), When the menu display process is terminated and the difference is determined to be information including the information specifying the page data transmission program 48, the search site name, and the first and second parameter groups (S402; YES), The process proceeds to step S403.

  In step S403, the web client device 20 generates screen data of the menu screen 52 based on the search site name and the first and second parameter groups. What is the web page displayed on the display device at this time? The menu screen 52 is displayed in another window. After the display, the menu display process is terminated.

  As described above, according to the computer network system of the second embodiment, when the reference page is a search result list page when the second web page search device 40 receives an HTTP request, the reference source A keyword is acquired from the URL of the page, and a menu screen 52 including link buttons 52b and 52c for executing a search using the keyword as a search condition and a list display of the search result as an instruction means is displayed together with a web page. Is incorporated into an HTTP response and transmitted to the request source. As a result, the web client device 20 that has sent the HTTP request sends the toolbar for the search site of the second web page search device 40 to the web client screen (not shown) displayed in the window by the web client program 21. If the tool program for incorporation is downloaded from the second web page search device 40, the web page is displayed and the menu screen 52 is displayed based on the information incorporated in the HTTP response. For this reason, the user of the web client device 20 as the request source, when the desired information is not included in the web page 53 displayed via the search result of the search site, the link button on the menu screen 52 The search result using the same keyword in this search site can be displayed by 52b and 52c.

  That is, when a part of information stored in the search database 33 used in the search site (first web page search device 30) is old, the destination web is jumped from the search result of the search site. Even if there is no desired information on the page 53, the link button 52b, 52c makes it easy to use the information desired by the user based on the search result at the jump destination site (second web page search device 40). Since the web page that contains it is displayed, the user is not confused.

  In the description of the first embodiment and the second embodiment described above, another search site (second web page) is used as an example of the destination site jumped from the search result of the search site (first web page search device 30). Although the search device 40) is mentioned, it is not limited to this. The destination site jumped from the search result of the search site is, for example, a so-called mail-order sales site that sells products such as electrical appliances, books, and generated food products, or the discontinuation of books, the discontinuation of music CDs, and models of automobiles It may be a so-called information providing site that provides information such as changes.

  That is, even if a site such as a mail-order sales site or an information providing site, the search database 43 that stores records in which web page data and URLs are associated with each other, and a search using the search database 43. If the program 45 (that is, the search engine) is provided (the robot program 44 may be omitted), the operation by the guidance program 46 according to the present invention and the search support function addition program 47 or the page data transmission program 48 Menu for displaying the effect (that is, the web page of the user's own site or other site desired by the user, or the web page (search result list page 54) in which link buttons for accessing such a web page are listed) The function and effect of displaying the screen 52) Rukoto can.
