It is very much not a solved problem. Because the implication behind search is not "well the result you need is technically in the result set", it's "the result you need as at the top", and that remains an extremely difficult problem for anything but a trivial scale.
Good support for regex and boolean operators helps a lot with that. But that requires user skill.
Then it's not a solved problem in any meaningful way.
