The server 101 stores data in a memory 102 for temporarily storing data, a document database 104 storing a plurality of document files (documents in SGML format, XML format, etc.) to be searched for character strings (keywords), and the document database 104. A search / display program 103 for creating a display information obtained by editing a document file so that a character string is searched for the document file and the search result position can be determined, and for speeding up the character string search The full-text search index file 105 in which character string (keyword) position information is stored.

  The memory 102 is configured in the RAM 202 on the hardware configuration of the server 101 illustrated in FIG. 2, and the document database 104, the search / display program 103, and the full-text search index file 105 are configured in the external memory 211. The document database 104 and the full-text search index file 105 may be configured on a server other than the server 101 connected to the network 106 as long as communication is possible. The server 101 can send and receive data to and from the client 107 via the network 106.

  The client 107 is equipped with a program or a web browser for inputting search conditions and displaying search results. The client 107 can send and receive data to and from the server 101 via the network 106. In FIG. 1, only one client is connected to the network 106, but a plurality of clients may be connected. Further, the connection configuration of various devices on the network 106 illustrated in FIG. 1 is merely an example, and there may be various connection configurations depending on applications and purposes.

  FIG. 2 is a diagram illustrating a hardware configuration of the server 101. The CPU 201 comprehensively controls each device and controller connected to the system bus 204. The ROM 203 or the external memory 211 has a BIOS (Basic Input / Output System) or an operating system program (OS) that is a control program for the CPU 201, and functions necessary for realizing functions executed by each server or each PC. Various programs to be stored are stored. The RAM 202 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program necessary for execution of processing into the RAM 202 and executing the program.

  An input controller (input C) 205 controls input from a pointing device such as a keyboard 209 or a mouse (not shown). A video controller (VC) 206 controls display on a display device such as a CRT display (CRT) 210. The display device may be a liquid crystal display as well as a CRT. The memory controller (MC) 207 is connected via an adapter to a hard disk (HD), a flexible disk, or a PCMCIA card slot that stores a boot program, browser software, various applications, font data, user files, editing files, various data, and the like. Controls access to an external memory 211 such as a connected CompactFlash (registered trademark) memory.

  A communication I / F controller (communication I / FC) 208 is connected to and communicates with an external device via a network, and executes communication control processing in the network. For example, Internet communication using TCP / IP is possible. Note that the CPU 201 enables display on the CRT 210 by executing outline font rasterization processing on a display information area in the RAM 202, for example. In addition, the CPU 201 enables a user instruction with a mouse cursor (not shown) on the CRT 210.

  The search / display program 103 is recorded in the external memory 211, and is executed by the CPU 201 by being loaded into the RAM 202 as necessary. The client 107 has a hardware configuration similar to that of the server 101, communicates with the server 101, transmits a search condition to the server 101 using a CGI (Common Gateway Interface), and the search result data is HTML. The data file is received from the server 101 as a format data file and displayed by the browser application.

  FIG. 3 is a diagram showing a basic processing flow of the document search system according to the present embodiment. The process of the document search system includes a search condition input process (step S301) and a full-text search process based on the search condition (step S302) and result display processing based on the full text search result (step S303).

  FIG. 4 shows an example of the configuration of the search condition input screen displayed on the display device 108 of the client 107 (FIG. 4A), and the search conditions input on the search condition input screen are transferred from the client 107 to the server 101. FIG. 4 is a diagram showing a configuration example (FIG. 4B) of a search condition table transmitted to the server and stored in the RAM 202 of the server 101. FIG. Note that the search condition table shown in FIG. 4B is also stored in the client 107 based on the input contents on the search condition input screen.

  In the search condition input process (step S301) which is the first processing step in FIG. 3, the search condition input screen (FIG. 4 (a)) displayed on the display device 108 of the client 107 is input by the user. The search conditions (401 to 405) are transmitted to the server 101 by using the CGI or the like when the search execution button 406 is pressed, and the server 101 receives these search conditions. In the example shown in FIG. 4A, search conditions 401 and 402 that search for a character string of one or more characters and a character string of one or more characters (hereinafter, this character string is referred to as a start character string). ) It ends with a character string of one or more characters (hereinafter, this character string is referred to as an end character string), and the number of characters between these two character strings is a designated number (hereinafter, this designated number is referred to as the number of characters between character strings). A search condition 403 for neighborhood search that is the following is set. Hereinafter, a search process for searching for a character string of one or more characters is referred to as a one-word search.

  The server 101 stores the received search conditions in the search condition table in a state as shown in FIG. That is, in the search condition table shown in FIG. 4B, the search condition input item 401, the search condition 2 input item 402, and the search condition input item 403 on the search condition input screen shown in FIG. The contents thus stored are stored corresponding to the respective search condition numbers (1 to 3). In the search condition table shown in FIG. 4B, “one character string” is a one-word search, and “two character string neighborhood 20” is a neighborhood search in which the number of characters between two character strings is 20 characters or less. The search target character string of the search condition 1 is “printing device”, the search target character string of the search condition 2 is “printer, and the search target character string of the search condition 3 is“ paper feed (start character string) ”, It indicates “inverted (end character string)”.

  FIG. 5 is a flowchart showing details of the full text search process (step S302), which is the second process step of FIG. By executing the processing shown in FIG. 5, the position information of each search target character string used when displaying the search result is acquired from the full-text search index file 105 and stored in the character string position information table shown in FIG. Stored.

  First, the CPU 201 of the server 101 determines whether or not the search condition received from the client 107 via the communication I / F controller 208 is a full text search (step S501). The search result display method is not executed, and the process ends.

  On the other hand, if the search condition is a full-text search, the CPU 201 further determines whether the search condition is a one-word search condition or a neighborhood search condition (step S502).

  If the search condition is one word search (step S502 / 1 word search), the CPU 201 searches the full text search index 105 for the position information in the document file of the character string to be searched from the top of the document file (step S503). ) And are registered from the top in the character string position information table 61 of FIG. 6 in the retrieved order (step S504). This character string position information table 61 is generated for each search condition of one word search. Here, two character string position information tables 61 are generated corresponding to each search condition (search condition 1, search condition 2). Will be.

  On the other hand, when the search condition is the search condition for the neighborhood search (step S502 / neighbor search), the search target character string (start character string, end character string) for the neighborhood search is processed by the processing shown in the flowcharts of FIGS. A character string position information table 62 (FIG. 6) for storing position information in the document file is created. The character string position information table 62 is also generated for each search condition for the proximity search. Here, one character string position information table 62 is generated corresponding to the search condition 3.

  In step S506 following step S504 or step S505, the CPU 201 determines whether the search condition determination (step S501) has been performed for all the search conditions stored in FIG. 4B (step S506). By repeatedly performing the search condition determination in step S501 for all the search conditions stored in FIG. 4B, the position information of the search target character string included in each search condition is converted to the character string position information table 61 in FIG. , 62 can be stored.

  FIG. 7 is a flowchart showing details of step S505 in FIG. 5, and shows a schematic operation of neighborhood search by the document search system.

  First, the CPU 201 acquires the search conditions for the neighborhood search that is currently being processed from the search condition table (FIG. 4B) (step S701), and there is a character string that matches the start character string of the search condition. The information about the position (hereinafter referred to as start character string position information) is acquired from the full-text search index file 105 and stored in the RAM 202 (step S702). In the present embodiment, the number of characters from the beginning of the document file to the first character of the start character string is used as start character string position information.

  Then, the CPU 201 determines whether or not a character string that matches the start character string exists in the document file (step S703). As a result of the determination, if a character string that matches the start character string does not exist in the document file, the CPU 201 ends the process of step S505, and proceeds to the subsequent process of step S506.

  In this way, if it is determined in step S703 that a character string that matches the start character string exists in the document file, the CPU 201 stores information on a position where a character string that matches the end character string of the search condition exists ( Hereinafter, the end character string position information) is acquired from the full-text search index file 105 and stored in the RAM 202 (step S704). In the present embodiment, the number of characters from the beginning of the document file to the first character of the end character string is used as the end character string position information.

  Then, the CPU 201 determines whether or not a character string that matches the end character string exists in the character file in the process of step S704 (step S705). As a result of the determination, if a character string that matches the end character string does not exist in the document file, the CPU 201 ends the process of step S505 and proceeds to the subsequent step S506.

  Subsequently, the CPU 201 uses the start character string position information and the end character string position information as position information for the document file in which the start character string position information and the end character string position information are acquired as described above. Are merged (incorporated) in ascending order from the smallest, and the merged position information (hereinafter referred to as merge position information) is stored in the RAM 202 (step S706).

  Next, the CPU 201 performs merge information adjacent position acquisition processing using the merge position information created in step S706 (step S707). In this merge information adjacent position acquisition process, first, the CPU 201 reads merge position information from the RAM 202, and determines whether or not there are a plurality of combinations of start character strings and end character strings within the number of characters between character strings. To do. As a result of this determination, when there are a plurality of combinations of the start character string and the end character string within the number of characters between the character strings, the closest combination among the combinations of the plurality of start character strings and end character strings. The combination of the start character string and the end character string is the optimum combination in the neighborhood search. On the other hand, when there is only one combination of the start character string and the end character string in the number of characters between character strings, that combination is determined as the optimum combination in the neighborhood search. The combinations of the position information of the start character string and the end character string that are optimally combined as described above are stored in the character string position information table 62. As a result, only the optimum combination is selected, and it is possible to prevent an unnecessarily increase in the number of character strings to be highlighted as search target character strings when displaying the search results, thereby providing a more easily visible display.

FIG. 8 is a flowchart showing details of the merge information adjacent position acquisition processing (S707).
First, the CPU 201 obtains a search condition for a neighborhood search (hereinafter referred to as a neighborhood search condition) that is the current processing target from the search condition table of FIG. 4B (step S801). Then, the CPU 201 sets a search pointer at the head of the merge position information created in step S706 of FIG. 7 (step S802), and the character string indicated by the search pointer is the neighborhood search condition acquired in step S801. It is determined whether or not it matches the start character string included in (step S803).

  If the result of this determination is that these character strings do not match, the CPU 201 moves the position of the search pointer to the next character string (step S804), and determines whether or not the position of the search pointer is the end of the merge position information. Determination is made (step S805). If the result of this determination is that the position of the search pointer is the last of the merge position information, the CPU 201 refers to the search condition table in FIG. 4B to determine whether or not the next neighborhood search condition exists. (Step S816). If the result of this determination is that the next neighborhood search condition exists, the next neighborhood search condition is acquired, and the search pointer is returned to the head of the merge position information (steps S801 and S802).

  In step S803, when the character string indicated by the search pointer matches the start character string of the neighborhood search condition acquired in step S801, the CPU 201 stores the position information of the search pointer in the RAM 202 as start character string position information. After storing (step S806), the search pointer is shifted to the next character string (step S807). Subsequently, the CPU 201 determines whether or not the position of the search pointer is the end of the merge position information (step S808). If the position of the search pointer is the end of the merge position information, refer to the search condition table. Then, it is determined whether or not a search condition for the next neighborhood search exists (step S816).

  On the other hand, if it is determined in step S808 that the position of the search pointer is not the end of the merge position information, the CPU 201 determines whether the character string indicated by the search pointer matches the start character string of the neighborhood search condition acquired in step S801. It is determined whether or not (step S809). If these character strings match as a result of this determination, the CPU 201 rewrites the recorded contents of the RAM 202 and updates the position information of the search pointer (step S806).

  On the other hand, if the character string indicated by the search pointer does not match the start character string of the neighborhood search condition acquired in step S801, the CPU 201 determines that the character string indicated by the search pointer is the neighborhood search condition acquired in step S801. It is determined whether or not it matches the end character string (step S810). As a result of the determination, if these character strings do not match, the CPU 201 moves the search pointer to the next character string (step S807).

  On the other hand, when the character string indicated by the search pointer matches the end character string of the neighborhood search condition acquired in step S801, the CPU 201 stores the current search pointer position information in the RAM 202 as the end character string position information. (Step S811).

  As described above, when the start character string position information is stored in step S806 and the end character string position information is stored in step S811, the CPU 201 determines whether the start character string position information and the end character string position information are between them. The distance (here, the number of characters) is obtained, and it is determined whether or not the obtained distance is less than or equal to the number of characters between character strings in the neighborhood search condition obtained in step S801 (step S812).

  If the distance between the start character string position information and the end character string position information is equal to or less than the number of characters between character strings as a result of the determination in step S812 performed in this way, the CPU 201 starts the process stored in step S806. The merge position information is marked so that the character string position information and the end character string position information stored in step S811 can be identified (step S813). Each combination of the start character string position information and the end character string position information marked in this manner is sequentially stored in the character string position information table 62.

  Then, the position of the search pointer is moved to the next character string (step S814), and it is determined whether or not the position of the moved search pointer is the last of the merge position information (step S815). If the result of this determination is that the position of the moved search pointer is not the end of the merge position information, the processing from step S803 to step S815 is repeated until the position of the search pointer reaches the end of the merge position information.

  On the other hand, if the position of the moved search pointer is the last of the merge position information in step S815, the CPU 201 refers to the search condition table in FIG. Is determined (step S816), and the processing from step S801 to step S816 is performed until the processing is performed for all the neighborhood search conditions. Thus, when the processing is completed for all the search conditions for the neighborhood search, the processing in step S505 in FIG. 5 is terminated, and the processing proceeds to the subsequent step S506.

  Next, a search result display method by the document search system will be described with reference to FIGS.

  The server 101 transmits the document file to be searched and the character string position information tables 61 and 62 corresponding to the document file shown in FIG. 6 to the client 107 (steps S9101 and S9102).

  Next, processing on the client 107 side will be described. It is assumed that all hardware configurations used in the following description are configured in the client 107, and the client 107 has the same configuration as the hardware configuration of the server 101 shown in FIG. Here, each hardware configuration will be described with the reference numerals in FIG.

  The CPU 201 of the client 107 stores the document file and character string position information tables 61 and 62 received from the server 101 via the communication I / F controller 208 in the external memory 211 or the RAM 202, and then the CRT 210 (display device 108). The search result moving display screen (FIG. 11) is displayed on the top (steps S9201 to S9203).

  Subsequently, the CPU 201 acquires the first record (record of search condition 1) of the search condition table (FIG. 4B), and sets the search target character string stored in the character string item in the acquired record as the movement target character. The movement target character string table 1201 is initialized by recording it as a column in the movement target character string table 1201 (FIG. 12) (step S9204). The movement target character string table 1201 is set as an initial condition by using the movement buttons 1105 to 1108 on the movement operation screen in FIG. 11 or at the start of the jump function, and is displayed near the head position of the frame (display area) by scroll display. This indicates that the character string to be subjected to position control is stored in the RAM 202. For example, here, “printing device” is stored as a display control target by the jump function. However, when the movement button 1106 on the right side of “printer” is pressed, “printing device” is stored in the movement target character string table 1201. "Printer" is overwritten.

  Subsequently, the CPU 201 acquires the search target character strings of the search conditions 1 and 2 and the start character string that is the search target character string of the search condition 3 from the search condition table (FIG. 4B), and the search condition 1 2, the character string position information stored in the first record from each character string position information table 61 corresponding to 2, and the start character string position information stored in the first record from the character string position information table 62 corresponding to the search condition 3 To get.

  Next, the client 107 associates the search target character string and the character string position information, the start character string and the start character string position information with the search conditions 1 to 3, respectively, and displays the display position in the state shown in FIG. The information is stored in the information table 1202, and the display position information table 1202 is initialized (step S9205).

  Subsequently, the client 107 executes scroll processing described later (step S9206).

  Subsequently, the client 107 waits for an action on the moving operation screen of FIG. 11 by the user. On the moving operation screen of FIG. 11, information indicating each search condition is displayed in each display item 1101 to 1103 based on each search condition 1 to 3 stored in the search condition table (FIG. 4B). In addition to being displayed, move buttons 1105 to 1108 and an end button 1109 for canceling the move instruction are prepared corresponding to the display items 1101 to 1104. In the example of FIG. 11, only the search target character string is shown in the case of one-word search, and the start character string and end character string that are search target character strings and the number of characters between the character strings are shown in the case of proximity search. .

  When the move buttons 1105 to 1108 are pressed (step S9207 / move button), the CPU 201 stores the search target character string of the search condition corresponding to the pressed move button currently in the move target character string table 1201. It is determined whether or not the character string matches the character string to be moved (step S9208). On the other hand, when the end button 1109 is pressed (step S9207 / end button), the search result display processing is ended.

  When the search target character string of the search condition corresponding to the pressed move button and the movement target character string currently stored in the movement target character string table 1201 match, the CPU 201 stores in the movement target character string table 1201. The character string position information of the same search target character string as the currently stored movement target character string is acquired from the display position information table 1202 and stored in the next record from the corresponding character string position information tables 61 and 62. Character string position information is acquired (step S9209).

  Subsequently, the CPU 201 determines whether or not the character string position information stored in the next record can be acquired from the character string position information tables 61 and 62 in step S9209 (step S9210). When it is determined that the character string position information stored in the next record has been acquired, the CPU 201 stores the acquired character string position information in the item 12021 corresponding to the search target character string in the display position information table 1202; The item 12021 is updated (step S9211).

  On the other hand, if it is determined that the character string position information stored in the next record could not be acquired, the CPU 201 displays the corresponding character string position information in the item 12021 corresponding to the search target character string in the display position information table 1202. The character string position information of the first record of the tables 61 and 62 is stored, and the item 12021 is updated (step S9212).

  If it is determined in step S 9208 that the search target character string of the search condition corresponding to the pressed move button does not match the movement target character string currently stored in the movement target character string table 1201, The CPU 201 stores the search target character string of the search condition corresponding to the pressed move button in the movement target character string table 1201 as a new movement target character string (step S9213).

  Subsequently, the CPU 201 acquires the character string position information stored in the first record from the character string position information tables 61 and 62 corresponding to the search condition including the same search target character string as the movement target character string, and the movement Stored in the item 12021 in the display position information table 1202 corresponding to the same search target character string as the target character string (step S9214).

  FIG. 10 is a flowchart showing the scroll display process (S9206) of the client 107. The display control process shown in this flowchart can be performed on a Web browser application using Dynamic HTML or the like if software written in C # and Java (registered trademark) Script is used.

  The CPU 201 acquires character string position information corresponding to the search target character string stored in the movement target character string table 1201 from the display position information table 1202 (step S1001).

  In step S1002, the CPU 201 generates an HTML data file based on the document file received from the server 101. Here, an HTML data file in which an anchor tag of <a name="hit">, for example, is inserted at the position indicated by the character string position information acquired in step S1001, and a tag for highlighting the position is further inserted. (For example, “DocData.html”). In addition to the generated HTML data file DocData.html, an HTML data file (for example, “Display.html”) that defines a frame using tags such as <FRAMESET> and <FRAME> is generated for display. A nested HTML data file Display.html in which an HTML data file DocData.html generated from document data is read is generated. Also, if there is an HTML data file generated from the previous document data, it is discarded and the HTML data file generated this time is used for display. Since the HTML data file related to the frame definition can be used in common, once it is generated, it can be used as it is.

  In step S1003, the frame displayed on the browser by referring to the anchor tag portion (<a name="hit">) of the HTML data file DocData.html generated from the document file by href = "hit". It is possible to display at the head of.

  As a modification, the height is measured with scrollTop from the part referred to by href and stored as a variable a. Using variable a, scroll (x, ay) (x and y are vertical to the display screen. (Fixed value indicating the amount of scroll movement in the horizontal and horizontal directions) can be controlled to have an offset from the first line.

  Step S1004 is actually performed by the browser application in its function, and is highlighted by the tag inserted for highlighting. As mentioned above, if you have an offset from the first line, it is possible to see the line immediately before the search target character string, so you can grasp the connection between the previous and next documents, and perform a highlighted display It becomes easier to determine whether the target character string is useful information.

  Transition of the display frame by the scroll display control as described above is shown in FIGS. FIG. 13 shows transition of display frames when the move button 1105 corresponding to “printing apparatus” is pressed on the move operation screen of FIG.

Control is performed so that the character string “printing device” is always displayed in the vicinity of the head position in the display frame 1302.

  FIG. 14 shows the transition of display frames when the move button 1106 corresponding to “printer” is pressed on the move operation screen of FIG. Reference numeral 1401 denotes a document file to be searched, and reference numeral 1402 denotes a display frame. As shown in FIG. 14, each time the move button 1106 corresponding to “printer” is pressed, the character string “printer” is sequentially displayed as a search result in the display frame 1302 from the top of the document file 1401 and always displayed. The character string “printer” is controlled to be displayed in the vicinity of the head position in the frame 1402.

  FIG. 15 shows the transition of the display frame when the move button 1107 corresponding to “paper feed @within 20 characters @ reverse” is pressed on the move operation screen of FIG. Reference numeral 1501 denotes a document file to be searched, and reference numeral 1502 denotes a display frame. As shown in FIG. 15, each time the move button 1107 corresponding to “paper feed @within 20 characters @reverse” is pressed, a start character string “paper feed” with 20 characters between the character strings from the top of the document file 1501 is displayed. ”And the end character string“ reverse ”are sequentially displayed in the display frame 1502 as search results, and the start character string“ feed ”and end character string“ reverse ”are always near the top position in the display frame 1502. It is controlled to be displayed.

  In the above embodiment, the server 101 has a search function, generates a position information table in which the search target character string exists in the document data, and creates HTML for scroll display using the software of the client terminal.
