Further, when IndexWriter writes new .del files, it's always to a new
(next generation) filename, so that the old .del file remains present.
This means if a fresh IndexReader is opened, it will load the old
.del file, and still not see any of IndexWriter's pending changes.

Lucene isn't relational at heart and may not be the right tool for
