Maybe something like this:
(define-key isearch-mode-map "\M-sft" 'isearch-cycle-filter-text)
(defun isearch-cycle-filter-text ()
"Cycle searching inside code vs strings/comments vs off."
(interactive)
(setq isearch-filter-predicates
(cond ((memq 'isearch-filter-text isearch-filter-predicates)
(cons 'isearch-filter-nontext
(delq 'isearch-filter-text isearch-filter-predicates)))
((memq 'isearch-filter-nontext isearch-filter-predicates)
(delq 'isearch-filter-nontext isearch-filter-predicates))
(t (cons 'isearch-filter-text isearch-filter-predicates))))
(setq isearch-success t isearch-adjusted t)
(isearch-update))
(defun isearch-filter-nontext (beg end)
"Test whether the current search hit is not inside text.
Return non-nil if the text from BEG to END is not inside
strings or comments."
(not (isearch-filter-text beg end)))
(put 'isearch-filter-nontext 'isearch-message-prefix "code ")
(defun isearch-filter-text (beg end)
"Test whether the current search hit is inside text.
Return non-nil if the text from BEG to END is inside
strings or comments."
(or (isearch-filter-comments beg end)
(isearch-filter-strings beg end)))
(put 'isearch-filter-text 'isearch-message-prefix "text ")
(defun isearch-filter-strings (beg end)
"Test whether the current search hit is inside strings.
Return non-nil if the text from BEG to END is inside strings."
(save-match-data (nth 3 (syntax-ppss))))
(put 'isearch-filter-strings 'isearch-message-prefix "string ")
(defun isearch-filter-comments (beg end)
"Test whether the current search hit is inside comments.
Return non-nil if the text from BEG to END is inside comments."
(save-match-data (nth 4 (syntax-ppss))))
(put 'isearch-filter-comments 'isearch-message-prefix "comment ")
