Subject Delete Parents without any children...
Date Wed, 01 Jul 2015 11:28:24 GMT
We have organised our segments in parent-child blocks and wish to
periodically delete parent-documents that don't have any children to
reclaim space via IndexWriter.deleteDocuments(Query)…

Is it possible to draft a Query that identifies such parents? Any help is
much appreciated…
