Welcome to the Lucene wiki! We use the wiki for brainstorming, maintainance of a FAQ, a free-for-all link database, and lots of miscellaneous snippets. Feel free to contribute. See (Obsolete) HowToContribute for more details.

Overview

Lucene is a text search engine API. Specifically, Lucene is the guts of a search engine - the hard stuff. You write the easy stuff, the UI and the process of selecting and parsing your data files to pump them into the search engine, yourself.

You can find the Lucene project at:http://lucene.apache.org/

Lucene is high-performance, scalable, full-featured, open-source, and written in Java.
