The difference acquired flag is not used for the next and subsequent processes by updating the flag of the record for which the XML output of the difference data has been completed to “1”.

  Further, as shown in FIG. 21, the output of the difference data XML 122 in step S1104 is divided into a plurality of folders to store XML files.

  In the XML output destination folder / file configuration shown in FIG. 21, folders with proposal numbers (1203, 1208, 1209) each having a proposal number of 10000 are arranged under the XML output folder 1201, and the processing of the XML creation unit 116 is performed. The XML files (1204, 1205, 1206) created in step 1 are arranged in the target proposal number folder for each proposal number.

  When the creation of the XML file for the target proposal number is completed, an in-folder completion flag 1207 is arranged in the folder for each proposal number.

  When the creation of all XML files is completed, an all folder completion flag 1202 is arranged under the XML output folder 1201.

  In the processing of the FIX creation unit 117, processing is performed by determining the XML file creation status from the presence or absence of the completion flag of each folder.

  Further, as shown in FIG. 22, the XML creation unit 117 acquires the processing target XML output folder 1201 (step S1201), and determines whether or not the all folder completion flag 1202 in the XML output folder 1201 exists. Determination is made (step S1202).

  If the all folder completion flag 1202 is present in step S1202, the process is completed and the process ends. If all folder completion flag 1202 is not present in step S1202, steps S1203 to S1203 are performed for all folders. The processing of S1208 is looped, and FIXML creation processing is performed for all folders by proposal number.

  First, it is determined whether or not an in-folder completion flag exists in each proposal number folder (step S1204). If an in-folder completion flag exists in step S1204, the next step after step S1203 to step S1208 is determined. The process proceeds to a loop process, and a process for creating a FIXML for the next folder is performed.

  If the in-folder completion flag does not exist in step S1204, the difference data XML 122 in the folder is read as an XML file reading process (step S1205), and the difference data FIX123 for creating the search index 119 is created as a FIX file creation process. Is created (step S1206).

  Then, after processing all the difference data XML 122 in the folder, an in-folder completion flag is arranged (step S1207), and the process proceeds to the next loop of steps S1203 to S1208.

  When the loop for all folders in steps S1203 to S1208 ends, an all folder completion flag 1202 is arranged (step S1209), and the process ends.

  Further, in the processing of the index creation unit 118, as shown in FIG. 23, the difference data FIXML 123 created by the FIXL creation unit 117 is acquired (step S1301), and the index creation is performed based on the difference data FIXML 123 obtained in step S1301. Processing is performed (step S1302), and the result is output to the search index 119.

  22 is processed in units of folders, for example, the processes in steps S1205 to S1207 can be performed on a plurality of folders in parallel.

  For this reason, the FIXML creation process can be performed at high speed by performing the FIXML creation process in parallel.

  As described above, in the present embodiment, parallel processing of search index creation processing is possible, and the processing time of the entire search index creation processing can be shortened.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say.

  For example, in the present embodiment, the search system has been described as the patent information management system. However, the present invention can be applied to any system or apparatus as long as it is configured to create a search index for searching for information.
