Search engine(s)

YaCy.net/en/ 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.

"A Search Engine with Clean and Pure Results"

Semantic search technology is based on a computerized system that understands content and query similar to how the human brain processes natural languages. Instead of matching the occurrence of words or symbols (as done in indexing systems), semantic search systems match concepts and their meaningful variations.

"Free People Search and Public Information Search Engine"

OpenFTS (Open Source Full Text Search engine) is an advanced PostgreSQL-based search engine that provides online indexing of data and relevance ranking for database searching. Close integration with database allows use of metadata to restrict search results.
