I'm trying to merge multiple nicknames of the same artist, so that when searching for one nickname the works done under other nicks would show up as well. (The artist adores deleting galleries and changing nicks.)

I've edited the "palestorm" artist entry with all the alternative nicknames, but searching for one of the nicks does not show works filed under other nicknames. What am I doing wrong?

Link to the artist entry for convenience: https://e621.net/artist/show/4235

put the old/lesser used name in upper box and new/more used in lower box. notice that you can put only one tag per box. you can add additional aliases by editing them into the forum post afterwards.
