title: ElasticSearch replication
body: <p>Can somebody provide some instructions on how to configure ElasticSearch for replication.  I am running ES in windows and understand that if I run the bat files multiple times on the same server, a separate instance of ES is started and they all connect to each other.</p>
  
  <p>I will be moving to a production environment soon and will have a three node set up, each node being on a different server.  Can someone point me at some documentation which gives me a bit more control of the replication set up.</p>
