---------------------------------------
Summary: Result Grouping: Number of results in group is not
according to specs
Key: SOLR-7939
URL: https://issues.apache.org/jira/browse/SOLR-7939
Project: Solr
Issue Type: Bug
Components: search, SolrCloud
Affects Versions: 4.7.1
Reporter: Esther Goldbraich
When using result grouping (group=true), Solr specs state the following about
the "rows" and "group.limit" params:
rows - The number of groups to return.
group.limit - Number of rows to return in each group.
We are using Solr cloud with a single collection and 64 shards.
When grouping by field (i.e. using the group.field parameter), the behavior is
as expected.
However, when grouping by query (using group.query), the number of documents
inside each group is affected by the rows param, instead of the group.limit
param.
This is different than what is mentioned in the specs.
Moreover, when switching to a non-sharded environment (64 collections, 1 shard
per collection), the behavior is different, and the number of docs inside each
group is affected by the group.query param, as expected.
