Subject Re: Find groups where at least one item matches a query
Date Sun, 05 Feb 2017 20:43:08 GMT
What about collapse and expand with overriden query. Something like
this (against 6.4 techproducts example):
http://localhost:8983/solr/techproducts/select?expand.q=*:*&expand=true&fq={!collapse%20field=manu_id_s}&indent=on&q=name:CORSAIR&wt=json

Note that the main document area contains the head document and the
expanded area contains the rest of them, up to provided/default limit.
For further info, see
https://cwiki.apache.org/confluence/display/solr/Collapse+and+Expand+Results

Regards,
   Alex.
