Right -- I think the main point, implicit in Will's answer, is that Gnus
doesn't index or search anything by itself. Nnir is its interface to the
search functionality provided by any given backend. Backends like nnimap
and nntp come with their own search abilities, but nnml is just files on
disk: you need a program to do the searching, then nnir will talk to
that program.
