Distributed Search Engines

YaCy

YaCy is a free search engine that anyone can use to build a search portal for their intranet or to help search the public internet. When contributing to the world-wide peer network, the scale of YaCy is limited only by the number of users in the world and can index billions of web pages. It is fully decentralized, all users of the search engine network are equal, the network does not store user search requests and it is not possible for anyone to censor the content of the shared index. We want to achieve freedom of information through a free, distributed web search which is powered by the world's users.


Possible applications: 

YaCy can operate as a single search appliance without networking with other peers. Such a search instance can be used for:
  • Search for projects - a combination of wikis, forums and websites
  • Topic-oriented search engine - combine a search for several web pages from different domains into a single search portal.
  • Companies can host their own search engine in order to help guard company secrets (a company may give away secrets with the search words employees submit to a search portal).
  • YaCy helps to preserve your anonymity when searching
