Abstract:
1. A pattern retrieving method for use with a pattern retrieval apparatus connected to a plurality of terminal devices through a network, comprising: receiving, from a terminal apparatus, a search condition set that comprises a search-pattern and a search-formula used when searching through data constituting a search target, together with a terminal apparatus identifier that identifies the terminal apparatus associated with a search condition set; storing search condition sets and terminal apparatus identifiers received from one or more of the terminal apparatuses into a search-condition buffer; and when investigation determines that no preceding search-process is in progress and that two or more search-patterns are same as each other among those stored in the search condition buffer; leaving a first of the same search-patterns in the search-condition buffer and erasing second and further ones being same to the first one; generating a search-pattern-variable table containing and correlating the search-pattern and a first variable that makes the search-pattern an associated value; further generating a search-query-formula-variable table containing and correlating, in a manner based on search-formulas and the terminal apparatus identifiers stored in the search-condition buffer and the generated search-pattern-variable table, a first search-query formula describing the search-pattern in a form using the first variable; and a second variable that makes the first search-query formula the associated value and further correlates the terminal apparatus identifier with a second search-query-formula describing the first search-query-formula-in a form using the second variable and the second variable that makes the first search-query-formula the associated value, and searching through a search-target database containing said data of the search-target according to the search-query-formula-variable table for extracting a data set that matches with the search condition set received from any of the plurality of terminal apparatuses as a search result; and transmitting the search result back to a relevant terminal apparatus.
