anchor.diff:  
   Statistics are returned in a format suitable for humans
   (eg `"exists_time": "1h"` or `"size": "1kb"`) and for computers
  -(eg `"exists_time_in_millis": 3600000`` or `"size_in_bytes": 1024`).
  +(eg `"exists_time_in_millis": 3600000` or `"size_in_bytes": 1024`).
   The human readable values can be turned off by adding `?human=false`
   to the query string. This makes sense when the stats results are
   being consumed by a monitoring tool, rather than intended for human
  
positive.code: 
  When appending `?pretty=true` to any request made, the JSON returned
  will be pretty formatted (use it for debugging only!). Another option is
  to set `format=yaml` which will cause the result to be returned in the
  (sometimes) more readable yaml format.
  
  
  
negative.code: Millimeter::    `mm` or `millimeters`
  Nautical mile:: `NM`, `nmi` or `nauticalmiles`
  
  The `precision` parameter in the <<query-dsl-geohash-cell-filter>> accepts
  distances with the above units, but if no unit is specified, then the
  precision is interpreted as the length of the geohash.
