Search engine for mail-index?

[Paul Ripke <stix%stix.id.au@localhost>]

Odd question, but what do people use to search the mail-index.netbsd.org
archives? I went looking for a specific email that I knew existed, and
none of the big search engines found it, except, interestingly, yandex.
I ended up letting mutt chew through my local archives to find it,
before discovering yandex.

My query was various forms of:
site:mail-index.netbsd.org ffsv2 corruption

And I was specifically looking for:
http://mail-index.netbsd.org/current-users/2019/08/19/msg036431.html

What do others use?
