Interesting you mention numDeletedDocs w.r.t. optimize - I need that information for exactly the same reason. Is there any good rule of thumb of knowing when it's best to call optimize? I know that during the internal merges Lucene does, deleted docs are removed. However there are those large segments that get merged very infrequently. Do you have some sort of *magic formula* that combines the num-deleted-docs, num-docs, and maybe other parameters?
