Hi Stefan, The score isn't "moved" from the "from" side to the "to" side and as far as I know there isn't a way to configure the scoring of the joined documents. The Solr join query isn't a real join (like in sql) and should be used as filtering mechanism. The best way is to achieve that is to put the join query inside a fq parameter.
