How about this version, which I've now checked in:

(defvar isearch-search-fun-function nil
  "Overrides the default `isearch-search-fun' behaviour.
This variable's value should be a function, which will be called
with no arguments, and should return a function that takes three
arguments: STRING, BOUND, and NOERROR.

This returned function will be used by `isearch-search-string' to
search for the first occurrence of STRING or its translation.")
