Geocoding search scope limitation?

Question

Google Maps

Good afternoon!
I can't understand what's going on.
I'm trying to limit the geocoding search area developers.google.com/maps/documentation/geocoding...
Something like this line

<script type="text/javascript" src="http://maps.google.com/maps/api/js?address=Petropavlovsk&components=administrative_area:KZ-SEV|country:KZ&sensor=true"></script>

Does not work, searches all over the world, if you do not specify the exact city, country in the search bar
