Just set or bind `isearch-filter-predicate' to
`isearch-range-invisible', to search only invisible text.

`C-h f isearch-range-invisible':

  isearch-range-invisible is a compiled Lisp function in ‘isearch.el’.

  (isearch-range-invisible BEG END)

  Return t if all the text from BEG to END is invisible.
