I tried
(add-function :before (local isearch-filter-predicate) 
#'org-fold-core--create-isearch-overlays)
and it somehow had no effect.

Steps I tried:

1. emacs -Q
2. Open a text file 1.txt with some text

A text file 1.txt with some text

3. M-: (defun yant/test (&rest _) (message "Foo"))
4. M-: (add-function :before (local isearch-filter-predicate) #'yant/test)
5. C-s txt <RET>
6. Switch to *Messages* buffer
7. Observe no "Foo" message

What am I missing?
