 * 		type array|string Order type, e.g. shop_order or shop_order_refund
 * 		parent int post/order parent
 * 		customer int|string|array User ID or billing email to limit orders to a

 * 			e.g. [email protected], 1, array( 1, 2, 3 ), array( array( 1, '[email protected]' ), 2, 3 )
 * 		limit int Maximum of orders to retrieve.
 * 		offset int Offset of orders to retrieve.

 * 		orderby string Order by date, title, id, modified, rand etc
 * 		order string ASC or DESC
 * 		return string Type of data to return. Allowed values:
 * 			ids array of order ids
 * 			objects array of order objects (default)
