Neeraj Lajpal commented on SOLR-6234: ------------------------------------- I have a doubt regarding query time join. Example: I have the document structure like this: parent1: id, important_category child1: id, _root_,brandid child2:id,_root_,brandid _root_ field of child doc contains value of parent's id. I want to use query time join. I want all the parent documents after applying boosts on children's fields and avg their scores, and then apply boost on important_category field on parent. My query is like this without boost on parent's field: {!scorejoin from=_root_ to=id score=avg multiVals=false}(brandid:1398^4 OR brandid:237^4.5) It is working fine. But, I want to apply boost to important_category field of parent also. If I will use fq it will not impact score, so I have to use q only. If I make q like : important_category:322^4{!scorejoin from=_root_ to=id score=avg multiVals=false}(brandid:1398^4 OR brandid:237^4.5) it is not showing any results.
