I'm keen for index-time joins (aka block joins), thus I've never looked into query-time ones. I even didn't ever know that there are two different query-time joins. This diverging might caused the fabulous drama: segmented vs top-level Ok. It seems like, Solr's query time join never scores https://github.com/apache/lucene-solr/blob/trunk/solr/core/src/java/org/apache/solr/search/JoinQParserPlugin.java#L535 But Lucene's JoinUtils does https://github.com/apache/lucene-solr/blob/trunk/lucene/join/src/java/org/apache/lucene/search/join/JoinUtil.java?source=cc#L78 Also Solr's join joins across different cores. -- Sincerely yours Mikhail Khludnev Principal Engineer, Grid Dynamics <http://www.griddynamics.com> <mkhlud...@griddynamics.com>
