Find a matching key
iterator find( iterator from, core::string_view key, ignore_case_param ic = = {}) const noexcept;
This function examines the parameters in the container to find a match for the specified key. The comparison is performed as if all escaped characters were decoded first.
The search starts at `from` and proceeds forward until either the key is found or the end of the range is reached, in which case `end()` is returned.
url_view u( "?First=John&Last=Doe" );
assert( u.params().find( "first" ) != u.params().find( "first", ignore_case ) );
Linear in `this->buffer().size()`.
