Artist, label, and place can already be searched by area's name, but it would be useful to allow searching by area's MBID in case the name would change (either due to a real change or a style change).
Note: It is already possible to search for recordings by release's MBID, for releases by release group's MBID, and so on.
It requires adding the following fields:
- for artist:
- for label:
- for place:
Both old and current MBIDs for the linked area should return results.
