• If you are trying to use Boolean operators, they must be ALL CAPS: lang anh tuan china chen ((((yang jui) OR (yang di))) OR (yang jie)) ((wong shiu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang anh tuan china chen ((((yang jui) or (yang di))) or (yang jie)) ((wong shiu) OR (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang anh tuan china chen ((((yang jui) or (yang di))) or (yang jie)) ((wong shiu) OR (wong siu)) ;*.
