/**

 * stories available on the server. </br></br>
 * //w  w  w  .  j  av a 2  s. c  o m

 * an example of a query that can be provided. This one searches for
 * all stories on the server who have contain the specified keywords in
 * their titles. </br></br>
 * 
 * {"query" : {"query_string" : {"default_field" : "title", "query" : "ugly AND red"}}}
 *

 * searching in must also be provided. A full example call would be: </br></br>
