• If you are trying to use Boolean operators, they must be ALL CAPS: yan ((yuan chang) OR (han chang)) yu chen ping lin ((kong siu) OR (kong young)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yan ((yuan chang) OR (han chang)) yu chen ping lin ((kong siu) or (kong young)) ;~".
• Adding a wildcard symbol may retrieve word variants: yan ((yuan chang) OR (han chang)) yu chen ping lin ((kong siu) or (kong young)) ;*.
