Rob, How do nested queries work with respect to this? If I build a boolean query one of whose clauses is a BooleanQuery with coord turned off, does just the nested query insides get left out of 'coord'? If so, then your answer certainly seems to be what the doctor ordered. --benson > > -- > lucidimagination.com > > --------------------------------------------------------------------- > To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org > For additional commands, e-mail: java-user-h...@lucene.apache.org > --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
