  * Iterate on index documents and perform $closure
  * Iteration uses ElasticSearch scroll scan methods
  * Note: Using setLimit(N) and setFrom(N) for query does not affect actual limit and offset (Limited by ES scan/scroll functionality, see Docs in link)
  *
  * See docs about $scroll in link:
  * @link http://www.elasticsearch.org/guide/reference/api/search/scroll.html
