Artists & Album Artist

I have here an example of not being able to find an artist/album by searching the main artist.
The reason is that the album artist field is not searchable and the artists tag is only reading 1 artist (from the right) and saves this entry in the DB. The other 2 artists entries are ignored.

When i search in ROSE/Androis connect for Per Oddvar Johansen i get the following results but not the album artist i am looking for.

per.oddvar.johansen.result

when i search for Helge Lien i get the following result but not yet the album artist i am looking for.

when i search for Torben Snekkestad i get the following result. Only the last search is giving me the album i want to listen to.

torben.snekkestad.result

I would want all artists entries in the tags to be written to the DB and searchable. Also there is a tag field “involved people” which has entries from other artists on an album as per MusicBrainz and Discogs tag entries.

As it is now with ROSE DB and ROSE Connect it is not possible to always find all artists. Yet this would be interesting while listening music with digital technique. A good many possibilities to use ROSE audio to best are lost because of this.
