This _looks_ o.k. (but make shure your newlines are really '\n').

How do you perform your 'test' search. Testing with Omega is a bit 
tricky since Omega will parse your Querystring (and most likely
stem the terms ...). Why don't you add:

 doc.add_term(Rtuxtux)

and then search for "Tuxtux". Note: The capital will force the Query-
parser into parsing the term as a "raw" term and prepend the 'R' tag
(read omaga/docs/termprefixes.txt if this isn't clear).
