I'm happy to announce the XWiki Lucene Plugin, developped by Jens Krämer.
This plugin brings full-text search to XWiki improving querying content as well as attachments (PDF, MS Word, OpenOffice Writer, XML/HTML).
We plan to use the Lucene Plugin to provide full-text searching accross all wikis of XWiki.com.
If you have your own installation of XWiki, you can try his Lucene plugin right away !
Thanks to Jens for his great work !
