search finds a subsequence of equal values in a sequence. search returns the first iterator i in the range [first1, last1 - (last2 - first2)) such that for any non-negative integer n less than last2 - first2 the following corresponding conditions hold:
*(i + n) == *(first2 + n)
 binary_pred(*(i + n), *(first2 + n)) == true

If no such iterator is found, last1 is returned. At most (last1 - first1) * (last2 - first2) applications of the corresponding predicate are done. The quadratic behavior, however, is highly unlikely.
