PROBLEM TO BE SOLVED: To provide a system in which a plurality of independent retrieval servers are loosely coupled, and the servers detect and delete duplicated entries in retrieval result responded from each retrieval server in the same retrieval condition. SOLUTION: An integrated retrieval control unit in a retrieval server 1100 determines hash algorithm commonly used in each retrieval control unit, when receiving an integrated retrieval request. Each retrieval control unit adds a hash value by the hash algorithm to retrieval result and responds to the integrated retrieval control unit. The integrated retrieval control unit detects and deletes duplicated entries based on the hash value. COPYRIGHT: (C)2013,JPO&INPIT |
