Editor: YaCy is a scalable personal web crawler and web search engine. One YaCy installation can store more than 10 million documents, but in a community of search peers YaCy can provide a search index of unlimited size./
Its easy!
Installation of YaCy takes only three minutes! Just download, decompress, start. Everything you need is included, no set-up of web servers, databases or anything else. No command-line interface, all administration tasks are done in a web front-end that is included in YaCy.
Decentralized Architecture
This is the public network that you can join to use and support a large-scale free and uncensored search:YaCy has a peer-to-peer web index exchange interface and it does not need a central server. Web searches are anonymized. No central log of your searches exist. Web crawls can be done collaborative with all other YaCy peers. Resulting indexes are organized in a distributed hash table.
Multimedia
YaCy can not only index texts from various file formats but also from different media contents. A search result shows interesting text, image, audio and video content with direct links to OGG, MP3, and video files.
