Awesome! Thanks a lot for your help, as I build my app I have with me a copy of Lucene in Action :) very nice book indeed.
I will verify what you just told me. :) what is strange is that I can see the documents using Luke, (in the debugger I had a break point before the search call and I inspected the document in Luke, so I believed the documents are there.)
