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. -- Adrien --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
