10678,search by a compatible key and default predicates,maxim.yegorushkin@…,Joaquín M López Muñoz,"Ordered and hashed indexes require predicates for comparing elements, which default to std::equal_to<Key> and std::less<Key> respectively.

At the same time find functions take a compatible key, that does not need to be convertible to Key.

Using std::equal_to<Key> and std::less<Key> breaks find when the compatible key is not convertible to Key because these predicates require both arguments to be of type Key.

Something like C++14 std::equal_to<void> and std::less<void> should be used as the default predicates.
