anchor.diff:  ==== Geo Bounds Aggregation on `geo_shape` fields
   
   The Geo Bounds Aggregation is also supported on `geo_shape` fields.
  +
  +If <<geo-bounds-wrap-longitude,`wrap_longitude`>> is set to `true`
  +(the default), the bounding box can overlap the international date line and
  +return a bounds where the `top_left` longitude is larger than the `top_right`
  +longitude.
  +
  +For example, the upper right longitude will typically be greater than the lower
  +left longitude of a geographic bounding box. However, when the area
  +crosses the 180° meridian, the value of the lower left longitude will be
  +greater than the value of the upper right longitude. See
  +http://docs.opengeospatial.org/is/12-063r5/12-063r5.html#30[Geographic bounding box] on the Open Geospatial Consortium website for more information.
   
   Example:
   
  
positive.code: --------------------------------------------------
  
  <1> The `geo_bounds` aggregation specifies the field to use to obtain the bounds.
  <2> `wrap_longitude` is an optional parameter which specifies whether the bounding box should be allowed to overlap the international date line. The default value is `true`.
  
  The above aggregation demonstrates how one would compute the bounding box of the location field for all documents with a business type of shop.
  
  
negative.code: === Geo Bounds Aggregation
  
  A metric aggregation that computes the bounding box containing all geo values for a field.
