title: ElasticSearch: Impact of setting a "not_analyzed" field as "store":"yes"?
body: <p>Suppose I have a string field specified as <code>not_analyzed</code> in the mapping. If I then add <code>"store":"yes"</code> to the mapping, will ElasticSearch duplicate the storage? My understanding of <code>not_analyzed</code> fields is that they are not run through an Analyzer, indexed <em>as is</em>, but a client is able to match against it. So, if a field is both <code>not_analyzed</code> and <code>store:yes</code>, this could cause ElasticSearch to keep two copies of the string.</p>
  
  <p>My question:</p>
  
  <ul>
  <li>If a string field is stored as both <code>not_analyzed</code> and <code>store:yes</code>, will there be duplicate storage of the string?</li>
  </ul>
  
  <p>I hope that's clear enough. Thanks!</p>
