title: Elasticsearch 2.x - Return a list of shingles
body: <p>I have a field  "searchtext" that I have provided a sub-field  "shingle" and I indexing that searchtext field with a shingles filter.  </p>
  
  <p>I need to get the list of shingles created for that field so that I can do some operations on that field.  When I retrieve the "searchtext.shingle" field, it just contains the original text.  </p>
  
  <p>Does that mean the shingle analyzer that I setup was not working, or that the I need to get the list of shingles back in a different way?  </p>
