title: Elasticsearch histogram, multiple interval types?
body: <p>Using Elasticsearch histogram functionality, i can put various 'ranges' of data into a bucket by specifying an interval. In this case '50':</p>
  
  <p>Price:
  0-50
  50-100
  100-150
  150-200
  200-250
  etc</p>
  
  <p>This works fine, but this returns an awfully long list of buckets. What I'd prefer is:</p>
  
  <p>0-50
  50-100
  100-200
  200-400
  400-1000
  1000+</p>
  
  <p>Or something of the likes. Is it possible to tell ES what intervals (/ranges) it should return?</p>
