Google's Geocoder returns wrong country, ignoring the region hint

Question

I\'m using Google\'s Geocoder to find lat lng coordinates for a given address.

    var geocoder = new google.maps.Geocoder();
    geocoder.geocode(
    {
            


        

Answer 1

I prefer a hybrid approach.

1. Use componentRestrictions to severely limit to country first.

2. If that doesn't yield enough results, search more broadly (and re-introduce bias if necessary)

   function MyGeocoder(address,region)
   {
       geocoder = new google.maps.Geocoder();
       geocoder.geocode({ 'address': address, 'componentRestrictions': { 'country': region } }, function (r, s) {
           if (r.length < 10) geocoder.geocode({ 'address': address /* could also bias here */ }, function (r2, s2) {
               for (var j = 0; j < r2.length; j++) r.push(r2[j]);
               DoSomethingWithResults(r);
           });
           else DoSomethingWithResults(r);
       });
   }
   
   function DoSomethingWithResults(r)
   {
       // Remove Duplicates
       var d = {};
       r = r.filter(function (e) { var h = e.formatted_address.valueOf(); var isDup = d[h]; d[h] = true; return !isDup; });
   
   
   // Do something with results
   }
