Google Places API仅针对某些地方返回ZERO_RESULTS

Question

对于某些地方，如机场或火车站，我的代码工作正常，输入完整的地址，如“16 CoursduMédoc，Bordeaux，France”，它也可以正常工作，但对于大多数地方，它不起作用，我得到ZERO_RESULTS状态。

我很困惑，无法找到问题所在。

以下是代码：

var drop = document.getElementById('destination');
var drop_autocomplete = new google.maps.places.Autocomplete(drop);
 drop_autocomplete.bindTo('bounds', map);
     drop_autocomplete.addListener('place_changed', function() {
                                            var placea = drop_autocomplete.getPlace();
                                            nom_arrivee = placea.name;
                                            arrivee_formulaire = placea.formatted_address;
                                   vicina = placea.vicinity;
                                   latitudeArrivee = placea.geometry.location.lat();
                                   longitudeArrivee = placea.geometry.location.lng();
                                            });
                   }
        google.maps.event.addDomListener(window, 'load', initialize);
