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