creator Frieder, Ophir creator Yee, Wai Gen A peer-to-peer (P2P) file sharing system is provided with an enhanced search method for a client node therein. A search from the client contains a primary search of metadata words and a secondary search of content file keys taken from the primary search results. The results of the secondary search are then used to rerank the results of the primary search before the client displays the results of the search to the user. Metadata distribution schemes can also be used to further enhance the utility of the system. Enhanced P2P file searching accuracy is thus provided. Applications for selective peer-to-peer communication may further be employed.
