Commit forces changes to stable storage, ensuring the changes are
there even if your jvm or computer crashes (fsync, etc)

But If you just want to make changes visible to searches, you can open
your reader from IndexWriter (see the NRT ctor) and call openIfChanged
to refresh the view when you need.
