I have this command

--8<---------------cut here---------------start------------->8---
;;;; Search the selected region
(defun site/isearch-region (start end)
  "Start isearch with the contents between START and END."
  (interactive (if (use-region-p)
                   (list (region-beginning) (region-end))
                 (user-error "No region")))
  (when (and start end)
    (deactivate-mark)
    (isearch-mode t)
    (isearch-yank-string (buffer-substring start end))))

(global-set-key (kbd "M-s M-s") #'site/isearch-region)
--8<---------------cut here---------------end--------------->8---

that searches for whatever is selected.  That also highlights every
occurrence.
