I understand the issue of the lucene doc id changing.  I'll probably look to 
see if I can delete stuff just based on some field that I have that I know 
won't change.  I've used the doc id for a long time, but maybe it's time for a 
change.  

Thanks for all of the input.

Subject: Re: Lucene 4.0 delete by ID

A top level document ID can change over time. For that reason you shouldn't 
rely on it. However if you know your index is stable or you keep track when a 
merge happes, you can use the IndexWriter#tryDeleteDocument method to delete a 
document by Lucene id. Deleting a document via a IndexReader is no longer 
possible.
