Abstract
We present Chora, a P2P web search engine which complements, not replaces, traditional web search by using peers’ web viewing history to recommend useful web sites to queriers. Chora is designed around a two-step paradigm. First, Chora determines which peers to query and then it executes a query across these peers. Each peer uses a desktop search engine to query their local web history and retrieve results ordered by relevance. To determine which peers to query, a small sketch of the information available from each peer is stored in a DHT. Peers with sketches indicating that they may have relevant information are queried. The query is dispersed through an ad hoc network connecting only those machines in the query and is optimized for getting good results as quickly as possible.
