The documentation says "The syntax for regular expressions is the same
as in Gnu Emacs." (sec 22.1).
My emacs documentation (v21.2.1) says about regexps:
> The special characters are `$', `^', `.', `*', `+', `?',

This is similar to GNU grep (basic) regular expressions, except for
the inclusion of '?', and the exclusion of character classes.
It's not clear from the documentation whether the other Emacs
constructs not listed in the OCaml manual entry are supported,
e.g. \(?: ... \), \`, \B, \<, etc.
