If I had to guess, I'd say you have some type of Analysis mismatch
between what you are indexing and what you are searching. Do you
really want to use the KeywordAnalyzer?
You might use Luke (http://www.getopt.org/luke) to have a look at your
index and see if that sheds some light.
Also have a look at the Lucene FAQ: http://wiki.apache.org/lucene-java/LuceneFAQ

Hi,
Mentioned below are snippets from my indexing and searching code.
For some
reason, I get zero hits all the time even for terms present in the
document
collection. Can somebody point out where I'm going wrong? I'm using
lucene-core-2.4.0.jar.
Thanks!
