IPC: G06F13/00
Filed: 2003-08-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a common search system capable of enhancing search techniques without getting in the way of friends or colleagues doing their jobs.  <P>SOLUTION: The common search system connects a plurality of clients, a proxy server, and an IM server to one another through a network. Each client sends inputted search conditions to the search server via the proxy server, displays the search results, and displays a history of search activities received from the IM server. The proxy server causes the search conditions and results sent from each client to be sent to the IM server as the search activities. The IM server causes each client's search activities received from the proxy server to be accumulated in a search activity DB as a history and managed; when the search activity DB is updated, the IM server sends to each client the history of search activities by each of the colleagues who are doing a common search. This enables the users to learn search techniques from other users skilled in search techniques, without interfering with their jobs.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
