The target of the broken link is:
	https://lists.gnucash.org/search/?idxinfo=gnucash-user
(The link itself is on mailman's info page for a given list.)

I get that there are no immediate plans to (re)implement search
locally, and that's cool; but more helpful than just returning a
404 error would be to put a static page at that URL that explains
what to do instead.
