Chris, The code you refer to in the blog is 5 years old! Some of the code is no longer valid with the newer Lucene jars. I wouldn't use it to test anything.
My suspicion is that your index itself is suspect. Let's see the code you use to build the index with a small data set that will show what you are trying to accomplish. BUT FIRST! Look at your built index with Luke before doing this to make sure that what you THINK you have in your index is really what you have. Luke is at http://www.getopt.org/luke/. This is probably THE most important tool you'll have in your arsenal and is pretty easy to use. You can query your index with it and see if it responds the way you think it should. You can enter your subject:"Good Morning" query and see what happens. If Luke can't find what you're querying for then your code won't.

I found the attached code on the Internet (see http://affy.blogspot.com/2003/04/codebit-examples-for-all-of-lucenes.html) and this fails too... Can you explain why? I would expect the first test to deliver 2 hits. I have tried with Lucene 2.0 and 2.3.2 jars and both fail.
