title: ElasticSearch dump full index to a csv file
body: <p>Is it possible to easily <code>export whole index</code>(all stored fields) of an elasticsearch cluster in a <code>.csv</code> file(possibly out of the box)?</p>
  
  <p>The alternative I can think is query the whole index and then convert the result... but I really don't like the idea of parsing a monstrous <code>json</code> since it contains some millions of documents!</p>
  
  <p>Are there any other ways or ideas to achieve the export?</p>
