Cubit

Cubit is a system that provides fully decentralized approximate keyword search capabilities to Azureus as a standard plugin. Approximate search means that you can use Cubit to find a movie, song or artist even if you don't know which spelling variation is used in the title or in her name. It gives you what you mean instead of what you asked for exactly, and returns the best results in the network in only a few seconds.

Cubit creates alongside BitTorrent a lightweight peer-to-peer network designed from the ground up to enable rapid and accurate approximate searches. It performs the searches without relying on any centralized components, and therefore is immune to legal and technical attacks targeting torrent aggregators. Additional technical details can be found in the approach section.
