> Initial request...
> bq. Switch max() and min() functions to work on multiValued fields so we can
> do sort=min(fieldname) asc and the sort would work on multiValued fields...
> ...this specific syntax has been spun off into SOLR-7853, but the underlying
> functionality s being implemented here using a new optional second argument
> to the {{field()}} function: {{field(multivalued_field_name,min)}} and
> {{field(multivalued_field_name,max)}}.
