Automatically wrapping I-search?

Question

In Vim I can :set wrapscan so that when I do an incremental search, the cursor jumps to the first match whether the first match is above or below the cursor.

In Emacs, if I start a search via C-s, the search fails saying Failing I-search if the first match is above the cursor. If I hit C-s again it then wraps the search, saying Wrapped I-search. How do I wrap and jump the cursor by default as in Vim, without having to C-s a second time?

EDIT: jurta's answer got me most of the way there. Thanks jurta! This is the behavior I wanted:

(defadvice isearch-search (after isearch-no-fail activate)
  (unless isearch-success
    (ad-disable-advice 'isearch-search 'after 'isearch-no-fail)
    (ad-activate 'isearch-search)
    (isearch-repeat (if isearch-forward 'forward))
    (ad-enable-advice 'isearch-search 'after 'isearch-no-fail)
    (ad-activate 'isearch-search)))

Answer 1

The easiest way to do this is to use the following defadvice:

(defadvice isearch-repeat (after isearch-no-fail activate)
  (unless isearch-success
    (ad-disable-advice 'isearch-repeat 'after 'isearch-no-fail)
    (ad-activate 'isearch-repeat)
    (isearch-repeat (if isearch-forward 'forward))
    (ad-enable-advice 'isearch-repeat 'after 'isearch-no-fail)
    (ad-activate 'isearch-repeat)))

When Isearch fails, it immediately tries again with wrapping. Note that it is important to temporarily disable this defadvice to prevent an infinite loop when there are no matches.
