Xindice full text indexing

[Andy Armstrong]

I've written a full text indexer that builds a Lucene index. That all 
seems to work fine. Now the hard part: what should the API be for 
querying the index? I can't find a spec for XPath full text queries 
although there is this document:
 http://www.w3.org/TR/2003/WD-xquery-full-text-requirements-20030502/

which sets out a few requirements. Any thoughts?
