Hi, I'm attempting result grouping <https://cwiki.apache.org/confluence/display/solr/Result+Grouping> with custom function in SolrCloud, by providing a _route_ , without success :~(
I know that group.func isn't supported in distributed searches, but in my case *I only need the query to gather data from one core*: as I index with "readerId" field as composite Id, then at query time I provide a _route_=reader1! (aka shard.keys). So I know all of my readerId documents are in the same shard. *Any way to pull this off?* Any comment on these leads? 1. Check the source code, as I guess there's something hardcoded that turns off distribution if group.func is present, then I could turn of this limitation - as I (think) know what I'm doing. 2.Implicit router? Example query: ...&group=true&group.func=concat(timebox(time_tdt, 0), stackId_s, ",")&_route_=reader1! Example docs (note the composite id): id reader_s time_tdt actor_s score_i stackId_s reader1!id1 reader1 2015-11-08T08:00:00Z actor1 3 stack1 reader3!id8 reader3 2015-11-10T22:01:00Z actor99 1 stack99
