You should probably be using your PerFieldAnalyzerWrapper in your
calls to QueryParser but apart from that I can't see any obvious
reason. General advice: use Luke to check what has been indexed and
read
http://wiki.apache.org/lucene-java/LuceneFAQ#Why_am_I_getting_no_hits_.2BAC8_incorrect_hits.3F
If none of these help, post again but showing what you are indexing as
well as how you are searching - the smallest possible test case or
self-contained program that shows the problem.
Or maybe someone else will spot the problem.
