    Are they not there already? If you look in the menus under "Options -
    Customize Emacs" there are for entries for apropos searches:

        Settings Matching Regexps...
        Options Matching Regexps...
        Faces Matching Regexps...
        Groups Matching Regexps...

Menu-bar  _Custom_  menu - it is a major-mode menu that appears when you are
in a Customize buffer.  Users might not think to look in the separate
Options menu at that point.
