Subject: Search for selected tex

Dear All,
I would like to be able to select some text with C-space and then look
for it inside the buffer.
I found some functions online which I modified to get:
;; a function to search the selected text
(defun my-search-forward (begin end)
(interactive (list (point) (mark)))
(let ((text (filter-buffer-substring begin end nil t)))
(goto-char (max begin end))
(let ((found-pos (search-forward text nil t)))
(if (not found-pos)
(progn
(goto-char begin)
(error "not found"))
(progn
(goto-char found-pos)
(set-mark (- found-pos (length text))))))))
(define-key global-map [(control q )] 'my-search-forward)
It is almost there but not yet...
If I highlight some text, I can look for it with C-q, but once at the
end of the buffer, it stops searching (whereas I would like it to search
from the beginning of the buffer).
If then I move to the beginning of the buffer, not everything above my
last position is selected, but also the function loses memory of what I
was looking for...
Anybody can give me some help? Apologies if there is already and emacs
command for that, but my online search was not fruitful.
Cheers
Lorenzo
