Like dired-isearch-filter-filenames adds own filter,
this could be implemented like:
(defun isearch-filter-no-search (beg end)
(not (text-property-not-all (min beg end) (max beg end)
'no-search nil)))
(add-function :before-while (local 'isearch-filter-predicate)
#'isearch-filter-no-search)
(insert (propertize "foo" 'display "bar" 'no-search t))

Maybe like this:
(defun isearch-filter-display (beg end)
(not (text-property-not-all (min beg end) (max beg end)
'display nil)))
(add-function :before-while (local 'isearch-filter-predicate)
#'isearch-filter-display)
(insert (propertize "foo" 'display "bar"))

Do you mean to match text in the display replacement, i.e. the string "bar"?
This is more complicated but it's possible by using get-text-property and
string-match to match the search string in the display property.
