Find artist does not list tracks with multiple artists

If a track has multiple artists and I go to Search - Find other artist - <Artist name> it will find all the tracks this artist is in.
If a track has a single artist and I go to Search - Find artist <Artist name> (there's no "Find other artist" option) it will only find the tracks with that single artist.
So for the same exact artist I can get 10 tracks in the former scenario and 20 tracks in the latter scenario.

they are different queries, one where the main artist is xxx and the other where artist xxx is associated with the track

Thanks for the explanation Steven.
That makes sense.

How can I find all the tracks with the artist if a track has a single artist?
It seems like that is only possible for tracks with multiple artists, because the Find Other Artists dropdown is only available there.
