rajanimaski commented on SOLR-8174:
-----------------------------------
It works, if the &group.format=simple is removed.
> group.ngroups results are not returned when documents indexed to same shard —
> with Document routing via composite keys

> Key: SOLR-8174
> URL: https://issues.apache.org/jira/browse/SOLR-8174
> Project: Solr
> Issue Type: Bug
> Components: search, SolrCloud
> Affects Versions: 5.3
> Reporter: rajanimaski
> Priority: Minor
>
> System setup —
> It’s a 2 sharded collection with Collection Name - anotherEtailSkus and the
> two shard core names are : anotherEtailSkus_shard1_replica1,
> anotherEtailSkus_shard2_replica1
> The collection is created with the following http rest api
> http://localhost:8983/solr/admin/collections?action=CREATE&name=anotherEtailSkus&numShards=2&replicationFactor=1&collection.configName=FileTest&maxShardsPerNode=2&router.name=compositeId
> Sample Documents Indexed —
> {"id":"125!1","groupedItemId_i":"1"}
> {"id":"7!1","groupedItemId_i":"2"}
> Problem Statement —
> Now, with grouping paramters, on any shard with _route_ param the response of
> group result is different. One of the shard returns group.ngroups and other
> does not. Please find the attached screenshot and query for reference in
> google doc link.
> Group query on a shard with the change in shard core only.
> http://localhost:8983/solr/anotherEtailSkus_shard2_replica1/select?q=*%3A*&fl=id,groupedItemId_i&wt=json&indent=true&group=true&group.format=simple&group.field=groupedItemId_i&group.ngroups=true&group.facet=true&_route_=125!
> -----groups.ngroups are not returned in response
> http://localhost:8983/solr/anotherEtailSkus_shard1_replica1/select?q=*%3A*&fl=id,groupedItemId_i&wt=json&indent=true&group=true&group.format=simple&group.field=groupedItemId_i&group.ngroups=true&group.facet=true&_route_=125!
> ----- group.ngroups are returned.
> Document routing via composite key should have routed documents with same key
> to same shards thus returning group results correctly— as per link [2]. But
> is not the case.
> Refer to the below google doc for detailed description.
