Lame/empty search results … my fault or Volumio?

Recent purchaser of Magna Mano streamer with Volumio. Thus far no problems. I am wondering, however, whether Volumio music search is intended to be competitive with other streaming platforms.

For example, when I search for Bill Charlap, nothing comes back. When I use supersearch, other artists appear. No sense using the streaming software at all (favorites, playlists, etc) if Bill Charlap doesn’t appear at all in my searches!
