what's the best way to search this list?

I have a potentially stupid question.  Before I ask it I'd like to see if
it has been answered on this list before, so I'm about to ask a potentially
even stupider question.

I can't see a way to search this list other than
1) browsing the archives day by day at
https://stat.ethz.ch/pipermail/r-sig-mac/
2) searching Google and hoping this list pops up.

Is there a search box somewhere that I'm missing?
Thanks. (https://www.youtube.com/watch?v=C7WeZbRbxwg&feature=youtu.be&t=28s)
