Hi,
The MoreLikeThis class in Lucene's contrib/queries project performs noise
word filtering based on the case-sensitive comparison of the terms against
the user-supplied stopwords set.

ah right - so the TermVector you use from the index will return mixed
and lower case versions of the same text.
One point to note - this would mean that of the 25 or so top terms
