Peer-To-Peer (P2P) networks like Gnutella improve some shortcomings of Conventional Search Engines (CSE) such as centralized and outdated indexing by distributing the search engines over the peers, which maintain their updated local contents. But they are designed for sharing and searching the contents in personal computers instead of websites. In this work, we propose a novel web information retrieval method called Site-To-Site (S2S) searching, which uses the P2P framework with CGI as protocol. It helps the site owners to turn their websites into autonomous search engines without extra hardware and software costs. In this paper, we introduce S2S searching with some related work. We also describe the system architecture and communication protocol. Finally, we summarize the experimental results, and show that S2S searching works well in one thousand sites.
