I noticed that `(point)' is not a reliable indicator to find
a matching point. It seems better to give two arguments
(match-beginning 0) and (match-end 0) to `isearch-success-function'.
So a correct example would be:
(set (make-local-variable 'isearch-success-function)
;; isearch only in function names
(lambda (mb me)
(save-match-data
(let ((re (cdr (assoc nil imenu-generic-expression))))
(and (save-excursion (beginning-of-line) (looking-at (car re)))
(>= mb (match-beginning (cadr re)))
(<= me (match-end (cadr re))))))))
