CONTENTS INDEXING RETRIEVAL SYSTEM AND RETRIEVAL RESULT PROVIDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a contents indexing retrieval system which filters and blocks contents by providing a means which implements the same contents blocking policy with a blocking engine by correcting a contents indexing retrieval engine. SOLUTION: A gateway 124 is used as an interface between a plurality of clients or an internal network 107 and the Internet 106. A proxy server having a cache and blocking proxy server 126 is usually inserted into the connection path from the internal network 107 to the Internet 106 to actualize the contents blocking policy, thereby increasing performance and management. The cache and blocking proxy server 126 can be connected to the gateway 124, or it can be connected directly on parallel to the internal network 107 and an external data transmission network 106.
