• If you are trying to use Boolean operators, they must be ALL CAPS: tong hui wang ((chun wang) OR (chen wang)) yang dan ((wong siu) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tong hui wang ((chun wang) OR (chen wang)) yang dan ((wong siu) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: tong hui wang ((chun wang) OR (chen wang)) yang dan ((wong siu) or (song shin)) ;*.
