       by calling <code>getGeocodingService()</code>. The <code>search()</code> method is used 
       to find a landmark by passing in the relevant parameters as defined in 
       <a href="http://developer.here.com/rest-apis/documentation/geocoder/topics/resource-search.html" target="_blank">Geocoder API</a>.
