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