Yacy: A Fully Decentralized P2P Search Engine, Install It On Ubuntu

Yacy is a very interesting search engine made entirely using Peer-2-Peer technologies. It is a decentralized project which means that its performances are only limited by the number of users contributing to the network.

Yacy has a strong emphasis on privacy. Due to its P2P nature, the network doesn't have a central authority resulting in a highly distributed search engine which is capable of indexing billions of webpages.

Yacy's Features:

• Independent search engine
• Privacy (Queries aren't stored and content isn't censured)
