For me it has allways been and will be "Various Artists" for the tag Albumartist, not just "Various".
Now, for Discogs search "ARTIST and ALBUM" you are out of luck with "Various Artists" and you get:

To fix this, insert a simple replace in
AppData\Roaming\Mp3tag\data\sources\Discogs Artist + Album.src
#[SearchBy]=Artist||$if2(%albumartist%,%artist%)||&artist=%s||Album||%album%||&release_title=%s
[SearchBy]=Artist||$if2($replace(%albumartist%,Various Artists,Various),%artist%)||&artist=%s||Album||%album%||&release_title=%s
If your Albumartist tags are a bit messed up, well fix it to whatever you like and change the replace accordingly.
If you use some kind of structured Albumartist like "Various Artists", "Various Artists Italian", "Various Artists German"… a regex could do the trick.
Or quick and dirty, just replace any Albumartist tag with "Various Artists" and created your own
Discogs Various Artist + Album.src
[SearchBy]=Artist||$if2($replace(%albumartist%,%albumartist%,Various),%artist%)||&artist=%s||Album||%album%||&release_title=%s
Fixed:
Let me know if I missed something.
Hope this helps.
