How to prevent google geocoder from returning results from other countries

Question

I'm using the google geocoder with an option to only return results from Germany

Here's the relevant part of my function

    ...
    var geocoder = new google.maps.Geocoder();
    geocoder.geocode({"address":address,"region":"DE" }, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            if (results[0].geometry.location) {
                completeGeo(results[0],address);
            } else {
                completeGeo(null,address);
            }

     ...

but if i geocode "cuvry" too find that street in germany

google returns for example "Cuvry, France" which is outside of the region parameter

How can I prevent google geocoder from returning results that are not in a certain Country? I mean return, not check in callback if country-code is matching.

Answer 1

This might work using component filters. "components":"country:DE"

var geocoder = new google.maps.Geocoder();
geocoder.geocode({"address":address, "componentRestrictions":{"country":"DE"} },
function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
        if (results[0].geometry.location) {
            completeGeo(results[0],address);
        } else {
            completeGeo(null,address);
        }
});

When I changed it to geocoder.geocode({"address":address, "componentRestrictions":{"country":"DE"} }, for germany my search results found vietnam.

I have changed it to this:

geocoder.geocode( {'address':address + ', Deutschland'}, function(results, status)

This works fine with countries name in own language.
