I'd like to announce the first release of EzMwLucene. This project provides a simplified Lucene search to Mediawiki. It is designed to be easy to install, configure, and run. It provides real-time, multiple field indexing and searching as well as text indexing of standard attachment types (pdf, xls, doc, ppt, vsd). The server is a self contained Java application (no application server needed), and the client portion is a standard Mediawiki extension. It is currently in production on an internal site with over 1000 users running on Mediawiki 1.13.

I welcome all feedback: questions, suggestions and offers to help improve it!
