YaCy: Technology, System components & Search-engine technology

YaCy (pronounced “ya see”) is a free distributed search engine built on the principles of peer-to-peer (P2P) networks, created by Michael Christen in 2003. The engine is written in Java and distributed on several hundred "YaCy-peer" computers, as of September 2006.
