Yes, just plain POSIX regexps.

Having multiple -s flags makes it an “or” but it influences the
relevance score:
https://www.gnu.org/software/guix/manual/en/html_node/Invoking-guix-package.html#index-searching-for-packages
So if you take the results with the highest score, that’ll probably be
those that match all the regexps.
HTH!
