My IndexReader and Searcher is open all the time. I am reopening it at constant interval.
Below are the code sequence. 1. DB optimize 2. Close writer 3. Open writer 4. Reopen new reader 5. Close old reader 6. Close old searcher. >>If the old IndexReader is still open when the optimize completes then the >>files it has open cannot be deleted. If reader should not be opened while doing optimize then User cannot perform search during the time period.

If the old IndexReader is still open when the optimize completes then the files it has open cannot be deleted. But, if that IndexReader hadn't been reopened in a while, it's possible it did not in fact have the files of the just-merged segments open (in which case the delete would succeed).
