I hesitate to submit this as a PR since they might simply have not been
implemented yet, as they're not listed in libstdc++/manual/status.html
explicitly.

The searchers are present, as stated in the status page.

The std::make_xxx_searcher / std::search is listed in P0220R1, the same paper
as the searchers ('Library Fundamentals V1 TS Components: Searchers').

FWIW, std::experimental::make_xxx_searcher / std::experimental::search (N3905)
are present, only the corresponding ones in std:: are missing,
