• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan yuan yi chen ((cheng ling) OR (cheng leong)) ((kong shiu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan yuan yi chen ((cheng ling) OR (cheng leong)) ((kong shiu) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan yuan yi chen ((cheng ling) OR (cheng leong)) ((kong shiu) or (wong siu)) ;*.
