\n serves no purpose here.
And you don't use arg NO-RECURSIVE-EDIT.

1. I already gave you another idea, off list.  What was wrong with it?

Put "[[:word:].,2]+" in a register or variable, and insert it after `M-e' during
isearch.

Or define a command to insert it after `M-e':

(defun foo () (interactive) (insert "[[:word:].,2]+"))
(define-key minibuffer-local-isearch-map (kbd "M-q") 'foo)

C-M-s M-e M-q C-s


2. FYI - A better mailing list for this kind of topic (a question about how to
use Emacs or Emacs Lisp) is address@hidden

HTH.
