Without an option this can be achieved with:

  (add-hook 'isearch-mode-end-hook
            (lambda ()
              (isearch-update-ring isearch-string isearch-regexp)))

Often previous useless search strings is a problem that I even use code
in .emacs in `isearch-mode-end-hook' that removes the search string
even on successful exit:

  ;; Don't push the search string into the search ring
  ;; (i.e. remove the stored search string)
  (if isearch-regexp
      (setq regexp-search-ring (cdr regexp-search-ring))
    (setq search-ring (cdr search-ring)))
