Erick Erickson created SOLR-12249:
-------------------------------------
Summary: Grouping on a solr.TextField works in stand-alone but not
in SolrCloud
Key: SOLR-12249
URL: https://issues.apache.org/jira/browse/SOLR-12249
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 6.6.2, master (8.0)
Reporter: Erick Erickson
I didn't test this with master. Under the covers in stand-alone mode, the "min"
function is silently substituted for the grouping, but that's not true in
SorlCloud mode. I broke this JIRA out separately to discuss whether it _ever_
makes sense to group by a tokenized text field.
Grouping by the min value in a field is at least consistent, but on a text
field I don't think it makes sense.
I propose that we explicitly dis-allow this in both stand-alone and Cloud mode,
especially now that there's the SortableTextField.
Comments?
