<p>In a full text search retrieval device (4) connected to a plurality of user terminals (3), a received retrieval condition and terminal device information are stored in a retrieval condition buffer (43). If it is determined that no preceding retrieving process is being performed, then a retrieval pattern variable table (46) and a retrieval request expression variable table (48) are generated. According to the retrieval request expression variable table (48), a database of the data to be searched is searched to extract a retrieval result matching the retrieval condition transmitted from any of the terminal devices (3), and the extracted retrieval result is transmitted to the appropriate terminal devices. Thus, although retrieval requests are continuously transmitted from respective users, a retrieval result can be returned to each user terminal in a similar response time as when a user terminal has sole use of the retrieval device (4). <IMAGE></p> |
