--------------------------------------

{quote} propose that we explicitly dis-allow this in both stand-alone and Cloud mode, especially
now that there's the SortableTextField.

> 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?
