Hello: I tried to use Collapsing Query Parser per following link: https://cwiki.apache.org/confluence/display/solr/Collapse+and+Expand+Results here is the query I am using http://<host_name>/solr/collection/select?q=groupId:*& fl=id,groupId,date&fq=%7B!collapse%20field=groupId%20sort=%27id%20asc%27%7D& expand=true&expand.rows=3&sort=date%20asc&expand.sort=id%20asc&rows=3
but I found the result is different from group query: http://<host_name>/solr/collection/select?q=groupId:*& fl=id,date,groupId&group=true&group.field=groupId&group. limit=4&group.ngroups=true&sort=date%20asc&group.sort=id%20asc&rows=3 it seems sort across collapsed document is not working. Can anyone help on this?
