• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yuhan) OR (wang xiuyan)) yang ((3 chin) OR (3 china)) chang ha kong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yuhan) or (wang xiuyan)) yang ((3 chin) OR (3 china)) chang ha kong siu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yuhan) or (wang xiuyan)) yang ((3 chin) OR (3 china)) chang ha kong siu ;*.
