I know that the reader reads a point in time, and that it won't see any updates unless you re-open the reader 'after' you commit or close the writer.
In my case, I will have the IndexWriter in a separate process, and the IndexReader running live in a webapp. I know this is thread safe, but is it safe to do this in a separate process, or do I need to close and disable all IndexReader features prior to updating the index in a separate process?
