Hoss Man commented on LUCENE-463:
---------------------------------

without providing any any explanation of how you are building the index, or how 
exactly you are executing your searches, I'm not sure that there is any way to 
understand the problem you are seeing

Please attach some code that demonstrates the probem.  

Ideally this should be in the form of a JUnit Test, so it can easily be 
incorperated into the existing unit tests -- but at a minimum people will need 
to see code for a standalone program with a main function that requires no 
input and builds up an index in either a RAMDirectory or in the current working 
directory and does a search/sort using the same method you are using in order 
to figure out what the problem might be.
