Lucene exposes commit() for exactly this reason -- on ungraceful shutdown (ie, you didn't succeed in calling IndexWriter.close), the index will be at the last successful commit() (or close(), which calls commit internally). As with Zoie, it's still the app's job to replay updates after the last commit. Note this is fully orthogonal to whether you use an NRT reader or not. NRT reader "simply" lets you search the full index, including un-committed changes.
