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. [2] [3] The engine is written in Java and distributed on several hundred computers, as of September 2006 [update], so-called YaCy-peers. Each YaCy-peer independently crawls through the Internet, analyzes and indexes found web pages, and stores indexing results in a common database (so-called index) which is shared with other YaCy-peers using principles of peer-to-peer.
Compared to semi-distributed search engines, the YaCy network has a distributed architecture. All YaCy-peers are equal and no central server exists. It can be run either in a crawling mode or as a local proxy server, indexing web pages visited by the person running YaCy on their computer. Several mechanisms are provided to protect the user's privacy. Access to the search functions is made by a locally run web server which provides a search box to enter search terms, and returns search results in a similar format to other popular search engines.
YaCy search engine is based on four elements: [4]
YaCy uses a combination of techniques for the networking, administration, and maintenance of indexing the search engine, including blacklisting, moderation, and communication with the community. Here is how YaCy performs these operations:
YaCy is available in packages for Linux, Windows, and Macintosh, and also as a Docker image. YaCy can also be installed on other operating systems either by manually building it, or using a tarball. [9] YaCy requires Java 8, OpenJDK 8 is recommended.
The Debian package can be installed from a repository available at the subdomain of the project's website. [10] [11] The package is not maintained in the official Debian package repository yet. [12]
