"i" is more similar to C-h C-i.

Adding the Gnus index node should work, something like this:

(info-lookup-add-help
 :mode 'emacs-lisp-mode
 :regexp "[^][()'\" \t\n]+"
 :doc-spec '(("(emacs)Command Index"  nil "`\\(M-x[ \t\n]+\\)?" "'")
             ("(emacs)Variable Index" nil "`" "'")
             ("(elisp)Index"          nil "^ - .*: " "\\( \\|$\\)")
	     ("(gnus)Index" nil "`" "'")))

You need to do `M-x info-lookup-reset' before it takes effect.
