NHibernate full text search documentation

For the net release of our software we want to offer our customers some form of full-text search or faceted search.

Our ORM is NHibernate 3.1.

There is plenty of Google hits for NHibernate 3.1 + search + documentation.

However not a single one that I found leads to a structured document with the strai开发者_如何学JAVAght dope on search in NHibernate.

Where's the docu at?

I don't know whether there is official documentation but I have used this in the past to get the basics up and running

Also, there is a book if you are interested :) book
