Subject Re: Lucene 2.2.0 Strange QueryParser behavior

OR is both a stopword and a reserved word.... In this
case you *probably* are getting hit by it being a stopword.
Changing your analyzer to not use stopwords is probably
the way to go, but beware that you should probably use the
same analyzer at index AND query time.

If you're using StandardAnalyzer, you're getting your case
folded, so if you change analyzers be aware of that.

Get a copy of Luke to see the effects of various analyzers on
queries and to examine the actual contents of your index, it's

PerFieldAnalyzerWrapper may be your friend <G>. It would
allow you to use a different analyzer for your "state" field than
others, which may be very useful.
