title: Creating a mapping for an existing index with a new type in elasticsearch
body: <p>I found an article on elasticsearch's site describing how to 'reindex without downtime', but that's not really acceptable every time a new element is introduced that needs to have a custom mapping (<a href="http://www.elasticsearch.org/blog/changing-mapping-with-zero-downtime/">http://www.elasticsearch.org/blog/changing-mapping-with-zero-downtime/</a>)</p>
  
  <p>Does anyone know why I can't create a mapping for an existing index but a new type in elasticsearch? The type doesn't exist yet, so why not? Maybe I'm missing something and it IS possible? If so, how can that be achieved?</p>
  
  <p>Thanks,
  Vladimir</p>
