searchable archives?

Can anyone point me to searchable archives of the list?  I usually use
Gmane, but it seems to be down.  Unless I'm mistaken, the official
archives <https://stat.ethz.ch/pipermail/r-sig-mixed-models/> aren't
searchable.

 - although https://www.r-project.org/search.html says "This engine lets
you search help files, manuals, and mailing list archives",
http://finzi.psych.upenn.edu/search.html only says it indexes "R
functions, package vignettes, and task views"

 - I can't get the search bar at
http://r-sig-mixed-models.r-project.narkive.com to work ...

  - I can't figure out whether Nabble mirrors r-sig-mixed-models

  More specifically, I'm trying to remember a generic critique of AIC
weights someone posted to the list a while back ...

  cheers
