Hi.

Maybe it's the same problem that I asked for and Otis Gospodnetic has just
answered (Many thanks !) :

If your analyzer convert tokens to lower case, then you must use lower case
value to search with IndexReader.
You can see it with TermEnum and look at values taht are really stored in
the index ...
