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
Lucene document IDs are not stable. You could add a field with an ID that
you maintain. Your query would then be just a TermQuery on the ID.

I'm currently converting some lucene code to 4.0. It appears that you are no
longer allowed to delete a document by its ID. Is that correct? Is my only
option to figure some kind of query (which obviously isn't based on ID) and do
the delete from there?
