In my experience, reopen will find all changes on an index, whether it was modified by the same process or not. If you're replicating over a network, you might need some barrier / lock around the reopen call to make sure the replicated index is complete. Obviously with something as fickle as a network, you may need some extra protection around this. It has worked best for me to replicate using IndexWriter wrapping some transport protocol.
