Peer-to-peer search that works

Dr. Djoerd Hiemstra presented a new generation of peer-to-peer search systems inspired by BitTorrent. In his peer-to-peer search approach, each peer is both a search client (a system that submits queries to the network) and a search server (a system that answers queries). Peers that submit a lot of queries, will have to answer a lot of queries as well. Peers may answer queries by providing their own indexed collection, or by caching search results. Djoerd presented simulations that show the effects of search result caching on query load balancing. He showed how the network can learn from the search result snippets without downloading or crawling the documents themselves. Finally, Djoerd showed an approach to include results from structured databases and other deep web search sites into the peer-to-peer search network.
