I was using mairix to search my local mail archives (nnml):

(setf (alist-get 'nnml gnus-search-default-engines)
      'gnus-search-mairix)
(setq gnus-search-mairix-remove-prefix
      (expand-file-name "Mail/archive/" "~"))

Matches look like

/home/micha/Mail/archive//sent/9076

Anything else you need to know?

When edebugging, the path stuff seemed to work ok, I saw that the
article numbers like "9076" were processed individually.  However I
didn't understand why the group names in the code were like ".sent",
".work", etc, with a leading dot, instead of "sent", "work".  At that
point I gave up.  I had the impression that the articles were not
correctly mapped to their groups and all were just discarded.
