Information search is a crucial part in peer-to-peer application systems. But existing search mechanisms are obsessed with low efficiency. We propose a multiple search model based on DHTs to solve the problem. Information of multiple keywords associated with the same resource is stored in one P2P node, and weighted vectors are used to denote information of the resource. Search queries are also expressed as weighted vectors. Then desired information can be located by matching vectors of queries and those of information. The simulation results show it can improve search accuracy significantly and reduce routing hops effectively.
