• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang xueman) OR (wang xiuyan)) yang ((13 china) OR (1 china)) chang ha kong siu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang xueman) or (wang xiuyan)) yang ((13 china) OR (1 china)) chang ha kong siu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang xueman) or (wang xiuyan)) yang ((13 china) OR (1 china)) chang ha kong siu ;*.
