Scott, did you mean the Lucene integer id, or the unique id field?

| A top level document ID can change over time. For that reason 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.
