title: Search in elasticSearch using alias name
body: <p>I have an alias pointing to two indices. I would like to use the alias name to search the documents rather than passing two index names and getting the results. </p>
  
  <p>Example : </p>
  
  <p>Like this : SearchResponse response = client.prepareSearch("alias")</p>
  
  <p>Not like this : SearchResponse response = client.prepareSearch("index1", "index2")</p>
