You'll have to call .commit() from the IndexWriter to make the changes externally visible.
The call IndexReader.reopen to get a reader seeing the committed changes; the reopen will be efficient (only open "new" segments vs the old reader). It's still best to use near-real-time reader when possible (ie, open the IndexReader from the IndexWriter), but it sounds like in your case this is not possible since writer and reader on different JVMs/machines across a network.
