PROBLEM TO BE SOLVED: To shorten a stand-by time by solving the problem that when a document is registered in a document database, and then full-text retrieval registration is executed, it is necessary to wait for a long time until the document is hit in retrieval processing. SOLUTION: Full-text retrieval is executed, and each time a hit document is decided, a hit frequency distribution table corresponding to document ID is updated. When the registration processing of full text retrieval is started, any non-hit document is erased from the first full-text retrieval data base based on the contents of the frequency distribution table when the registration processing of the full-text retrieval is started so that the retrieving time can be shortened. The erased document is registered in a second full-text retrieval data base again. The actual retrieval is executed in the order of the first and second full-text retrieval data bases, and the document whose hit frequency is high in the second full-text retrieval data base is registered in the first full-text retrieval data base again.
