<p><P>PROBLEM TO BE SOLVED: To retrieve query definition information by a free keyword with performance same as when of using the query definition information and retrieving data without using both of them. <P>SOLUTION: A design part 11 generates the query definition information. A division part 12 extracts a character string included in the query definition information to be used for character string information 21, sets a character string ID to a part from which the character string is extracted instead of the character string, and sets the query definition information set with the character string ID as query definition information 22 except the character string. A keyword retrieval part 15 acquires a retrieval keyword 3 for retrieval of the query definition information from a user, and retrieves the character string information 21 corresponding to the retrieval keyword 3 to retrieve the query definition information by the free keyword. A merg part 13 replaces the character string ID with the corresponding character string in the character string information 21 so for count retrieval of data, and merges the query definition information 22 except the character string and the character string information 21 to reproduce the query definition information. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
