 #### Example:
 
     <template is="dom-bind">
-      <google-map-search map="[[map]]" libraries="places" query="Pizza"
-                         results="{{results}}"></google-map-search>
+      <google-map-search map="[[map]]" query="Pizza" results="{{results}}">
+      </google-map-search>
       <google-map map="{{map}}" latitude="37.779"
                   longitude="-122.3892">
         <template is="dom-repeat" items="{{results}}" as="marker">
           <google-map-marker latitude="{{marker.latitude}}"
                              longitude="{{marker.longitude}}">
             <h2>{{marker.name}}</h2>
             <span>{{marker.formatted_address}}</span>
           </google-map-marker>
