What about doing this (unrelated parts stripped, just as an example):

(defun dired-isearch-filter-filenames (beg end)
  (let ((beg (min beg end))
        (end (max beg end)))
   (and (get-text-property beg 'dired-filename)
        (or (eq (char-after end) ?\n)
            (get-text-property end 'dired-filename)))))

This assumes that file names are convex and followed by a newline.

Surprisingly that doesn't work.  Even with search-invisible nil I get
exactly the same matches, i.e., also the invisible text is being
matched.  What did I miss?
