Geocrawler no longer provide a search facility for the NetBSD mailing
lists (it used to be on a per list basis and was extremely useful), even
both their site and http://www.netbsd.org/MailingLists/ mention such a
service. In addition, the rudimentary search facilities at
http://mail-index.netbsd.org/ have also been discontinued.

The mailing list archives are a rich source of knowledge, but they are of
little use if there are no search facilities.
