I've read all posts in this topic, but it didn't help me.
I would like to achieve searching for Richie Hawtin and gettings results for all of his aliases (Robotman, Plastikman, F.U.S.E, etc.). What is the best and correct way to do it?
P.S. I am taking all music with MusicBrainz Piccard using MusicBrainz databes. If this is of any help. 
Hey. Since then, i've just been manually attributing aliases through the artist splitter. Just know it's a lot of work and not everyone has the time in the world to do this though.
You just have to settle for a specific general name you want to attribute aliases to, and stash the real name in the artist splitter (aka just the "performer" tag) somewhere.
I generally do this then, see here (Sampling Masters being an alias of Shinji Hosoe):


It's kinda wacky but gets the job done when you search for a specific artist, and it doesn't affect the display artist field since it's pretty much stashed away.
