Google Maps Autocomplete - only cities and postal code

Question

is it possible to restrict the autocomplete search only to cities and postal code?

This won't work:

autocomplete = new google.maps.places.Autocomplete(
                    /** @type {!HTMLInputElement} */(document.getElementById('autocomplete')),
                    {types: ['(cities', '(postal_code)'], componentRestrictions: {country: "de"}});

Maybe this is right?

autocomplete = new google.maps.places.Autocomplete(
                    /** @type {!HTMLInputElement} */(document.getElementById('autocomplete')),
                    {types: ['(regions)'], componentRestrictions: {country: "de"}});

But autocomplete also show some results outside my restricted country, why?

Some suggestions?

Solution

autocomplete = new google.maps.places.Autocomplete(
                    /** @type {!HTMLInputElement} */(document.getElementById('autocomplete')),
                    {types: ['(regions)'], componentRestrictions: {'country': "de"}});
