std::experimental::search - std::experimental::search
Defined in header <experimental/algorithm>
template<class ForwardIterator, class Searcher>
ForwardIterator search( ForwardIterator first, (library fundamentals TS)
ForwardIterator last,
const Searcher& searcher );
Searches the sequence [first, last) for the pattern specified in the
constructor of
searcher.
Effectively executes searcher(first, last). (until C++17)
Effectively executes searcher(first, last).first. (since C++17)
Searcher need not be CopyConstructible.
The standard library provides the following searchers:
default_searcher standard C++ library search algorithm implementation
(class template)
boyer_moore_searcher Boyer-Moore search algorithm implementation
(class template)
boyer_moore_horspool_searcher Boyer-Moore-Horspool search algorithm
implementation
(class template)

Returns the result of searcher.operator(), that is, an iterator
to the location at
which the substring is found or a copy of last if it was not found.
