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.
