 *  Note that the only queries supported for `ListDeliveryVehicles` are
 *  on vehicle attributes (for example, `attributes.<key> = <value>` or
 *  `attributes.<key1> = <value1> AND attributes.<key2> = <value2>`). Also, all
 *  attributes are stored as strings, so the only supported comparisons against
 *  attributes are string comparisons. In order to compare against number or
 *  boolean values, the values must be explicitly quoted to be treated as
 *  strings (for example, `attributes.<key> = "10"` or
 *  `attributes.<key> = "true"`).
 *  The maximum number of restrictions allowed in a filter query is 50. A
 *  restriction is a part of the query of the form
 *  `attribute.<KEY> <COMPARATOR> <VALUE>`, for example `attributes.foo = bar`
 *  is 1 restriction.
