Subject Re: Delete Parents without any children...

Hi Ravikumar,

You need to run a BooleanQuery with two clauses:
 - a must clause that matches all parent documents
 - a must_not clause that matches all parents that have children

Building this second clause can be done easily with a
ToParentBlockJoinQuery around a child query that matches all your
children documents.
