The only other required config is the "remove-prefix" key, which tells
Gnus how to strip off the leading part of the absolute filename of
search results. Right now it might require an explicit absolute path,
not a tilde expansion, so you'd probably need:

(setq gnus-select-method '(nnnil "")
      gnus-secondary-select-methods
      '((nntp "news.gwene.org")
	(nnmaildir "yoctocell"
		   (directory "~/.local/share/mail/yoctocell@disroot.org")
                   (gnus-search-engine gnus-search-mairix
                     (remove-prefix "/<absolute>/<path>/.local/share/mail/yoctocell@disroot.org")))))

That's not very reasonable, so I'll add a call to `expand-file-name' in
a bit. But specifying an absolute file name doesn't hurt, either.

Check first with `gnus-search-use-parsed-queries' to nil, and let me
know if it still doesn't work.
