Structured P2P network is highly efficient in resources search, but it only supports single-keyword search rather than semantics search. This paper put forward a search algorithm for structured P2P network: SABOSR, which is based on semantic routing. The algorithm classifies the node resources into several categories in terms of their semantic similarity degree, and each category is managed by a virtual node. The algorithm can study searching experience from its history search information, and efficiently cluster neighbor nodes base on similar semantics. The simulation experiments demonstrate that SABOSR algorithm makes the structured P2P network to efficiently support semantic search, and without any loss of its original advantages.
