anchor.diff:  // TEST[setup:twitter]
   
   The `source` section supports all the elements that are supported in a
  -<<search-request-body,search request>>. For instance only a subset of the
  -fields from the original documents can be reindexed using source filtering
  +<<search-request-body,search request>>. For instance, only a subset of the
  +fields from the original documents can be reindexed using `source` filtering
   as follows:
   
   [source,js]
  
positive.code: 
  `throttled_until_millis`::
  
  This field should always be equal to zero in a delete by query response. It only
  has meaning when using the <<docs-reindex-task-api, Task API>>, where it
  indicates the next time (in milliseconds since epoch) a throttled request will be
  executed again in order to conform to `requests_per_second`.
  
negative.code: // CONSOLE
  // TEST[continued]
  
  which will return:
  
  [source,js]
