To be fair the second result seems consistent with the Solr grouping logic :
*First Query results (Suspicious)* 1) group.sort= score desc -> select the group head as you have 1 doc per group( the head will be the top scoring doc per group) 2) sort=score asc -> sort the groups by the score of the head ascending ( so the final resulting groups should be ascending in score) *Second Query results ( CORRECT)* 1) group.sort= score desc -> select the group head as you have 1 doc per group( the head will be the top scoring doc per group) 2) sort -> sort the groups by the score of the head ( so the final resulting groups are sorted descending) Are we sure the the sort is expected to sort the groups after the grouping happened ? I need to check the internals but I agree the current behaviour is not intuitive.
