In this paper, the search algorithm based on the direction - DBS algorithm is proposed. Through the methods designated the search direction, the shortcoming of the massive redundant search message are solved, when searching by flooding and its improved algorithm in unstructured P2P network. The problem that the search speed of flooding and its improved algorithm is slow is solved through dividing the search region and improving search parallelism. Finally, the simulation of the DBS algorithm and its improved algorithm by program is realized. The algorithm was analyzed through the experimental results. The experimental data show that the DBS algorithm is correct and viable, and greatly improves the search performance in unstructured P2P network.
