YaCy is a personal Web crawler and Web search engine. It's also a P2P-based Web index exchange network without a central server and no censoring possibility. Web crawls can be done locally, or you can trigger a collaborative Web crawl with all other YaCy peers. YaCy is fun to use and shows interesting text, image, audio and video search results with direct links to Ogg, MP3, and video files. It has a cooperative bookmark system and many Web publishing functions.
An auto-updater and support for multiple search networks have been added, and the option to index intranet sites in separated networks has been enabled. Some interface functions have also been enhanced.
