Searching for "Albumartist Album" in MusicBrainz and discogs

Looking for album and track-information mostly makes only sense if your searching parameters include albumartist and album.
This becomes clearly obvious if you search for the album "Greatest Hits". :wink:

With the scripts for itunes, amazon, Musik-Sammler it is possible (or I myself made it work) to look for the albumartist/artist and the album.

Is this possible for MusicBrainz and discogs too?
I found no easy way to change the script in that way as I did in others scripts (just changing "Search by"). and this easy way is the only way for me as I don't have enough knowledge to do it different.
