title: Highlight country around the border from your search area only
body: <p>I have to make a <a href="https://www.google.com/fusiontables/DataSource?docid=1WkOReHYpsvNiACHeL5tOxsuYO-nRmzOdXm7B-GDo" rel="nofollow">KML file</a> from the Dutch country.</p>
  
  <p><strong>What I want to do is:</strong></p>
  
  <p>I want to Highlight only the countries around the border from my search area.</p>
  
  <p><strong>Example:</strong></p>
  
  <p>As a user searches on 'Amsterdam'. There are like 9 (Zaandam, Amstelveen, Hooftdorp, Diemen, Duivendrecht, ......) other states that are connected with Amsterdam. I want only these 9 states to have a highlight.</p>
  
  <p>So all I want to do is Highlight the states that are connected on the border from the user search area. </p>
  
  <p>Can anybody help me here? </p>
  
  <p><strong>Example my code I have till now:</strong></p>
  
  <pre><code>function codeAddress() {
      var address = document.getElementById("search-input").value; // get search result
      geocoder.geocode({'address': address}, geocoderCallback);
  }
  
  function initialize() {
      var mapOptions = {
          zoom: 12,
          center: new google.maps.LatLng(lat, lng),
          disableDefaultUI: true,
          mapTypeControl: false,
          zoomControl: true
      }
      map = new google.maps.Map(document.getElementById('map-canvas'),
          mapOptions);
      geocoder = new google.maps.Geocoder();
      geocoder.geocode({'address': address}, geocoderCallback);
  
  
  
  }
  
  // function for hilight
  function geocoderCallback(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
          map.setCenter(results[0].geometry.location);
