This is known & expected. Lucene does not update the terms dictionary (meaning which terms are in the index, and their frequency) in response to deleted docs.
It does update TermDocs enumeration, ie once you get the TermDocs for a given term and step through its docs, the deleted docs will not be returned. One workaround is to call IndexWriter.expungeDeletes, but that's a costly operation (forces merges of any segments containing deletes). https://issues.apache.org/jira/browse/LUCENE-1613 was opened to gather use cases / issues on this... if this is impacting your application, can you post some details to that issue?
