Many thanks for your answer, it was very complete.
Isearch+ is pretty much what I want :)

Also i had this snippet to force isearch to always put the cursor in
the beginning of the match:

(defun custom-goto-match-beginning ()
  "Use with isearch hook to end search at first char of match."
   (when isearch-forward (goto-char isearch-other-end)))

which i just changed to:

(defun custom-goto-match-beginning ()
  "Use with isearch hook to end search at first char of match."
  (when isearch-forward (exchange-point-and-mark)))

to work with isearch+.

Cheers,
