This would be incredibly helpful! Voting up.

As a side note, I actually tried for a while to do this as it wasn't clear to me from the documentation on min() that it couldn't be done. As it stands I'm having to do sorting, and therefore pagination, on the client side which is a real drag, and necessitates bringing back the entire result set every time a new page is required.

> ...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)}}.
