• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (dong di)) ya yuan feng juan kang ((kong siu) OR (((dong skin) OR (dof skin)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) or (dong di)) ya yuan feng juan kang ((kong siu) or (((dong skin) OR (dof skin)))) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yan) or (dong di)) ya yuan feng juan kang ((kong siu) or (((dong skin) OR (dof skin)))) ;*.
