Here's your answer I think....
http://wiki.apache.org/lucene-java/LuceneFAQ#head-133cf44dd3dff3680c96c1316a663e881eeac35a
In a nutshell, wildcard queries are not passed through an analyzer, although
they are
lower-cased by default. So you're indexing foobar but searching on _foobar
(after rewrite)....
But since searching on "_FooBar" *is* passed through the analyzer, it works.
query.toString is your friend <G>......
at least I think....
