Mikhail Khludnev updated SOLR-10521: ------------------------------------ Attachment: SOLR-10521.patch [^SOLR-10521.patch] here we go! the valuesource syntax is {{sort=childfield(field,$bjq) asc}} or {{sort=childfield(field) asc}} assuming {{$q}}. The sad thing is that, I cant' improve QueryComponent change (it's brilliant already). So, far it can be only used for sorting. But can be extended to regular value source functionality in future. This might even work numerics, but I havent' checked it yet. Reviews and suggestions are urgently required! > sort by string field of the nested child when searching with {!parent} > ---------------------------------------------------------------------- > > Key: SOLR-10521 > URL: https://issues.apache.org/jira/browse/SOLR-10521 > Project: Solr > Issue Type: New Feature > Security Level: Public(Default Security Level.
