title: Elastic search and "databases"
body: <p>Sorry for the ambiguous title, couldn't thing of anything better fitting.</p>
  
  <p>I 'm exploring Elastic Search and it looks very cool. My question is conceptual since I 'm used to sql. </p>
  
  <p>In Sql, you have different databases and you store the data for each application there. Does the same concept exist in ES? Or is all data from all my application going to end up in the same place? In that case, what are the best practices to avoid unwanted results from unfitting data?</p>
