  * The list of fetched fields.

  * The fields are returned using a fully qualified name format, however, the format differs slightly from that used by
  * the query operations.
- * 
+ *
  * Fields which contain nested JSON objects are assigned a type of "nested".
- * 
+ *
  * Fields which belong to a nested object are prefixed with `.properties` (for example, `warnings.properties.severity`
  * means that the `warnings` object has a property called `severity`).
- *

  * Fields returned from the News collection are prefixed with `v{N}-fullnews-t3-{YEAR}.mappings` (for example,
  * `v5-fullnews-t3-2016.mappings.text.properties.author`).
