Would it be possible to enhance IndexReader to report the "version" of the index it is using, and to report if a newer version of the index exists, eg perhaps #version and #current_version? This would allow a long running IndexReader to detect that a new index version is available, which is a problem if the IndexWriter updates the index from another process. For example, I am planning to divide my application into two apps, one which services reader requests, and the other which periodically updates the index if needed.
