Michael McCandless commented on LUCENE-887:
-------------------------------------------

That's right.

Close calls flush() and flush() waits for any in-flight addDocument() calls to finish.

> Adds the ability to IndexWriter to interrupt an ongoing merge. This might be necessary
when Lucene is e. g. running as a service and has to stop indexing within a certain period
of time due to a shutdown request.
> A solution would be to add a new method shutdown() to IndexWriter which satisfies the
following two requirements:
> - if a merge is happening, abort it
> - flush the buffered docs but do not trigger a merge 
> See also discussions about this feature on java-dev:
