• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yao) OR (ganga ya)) yang kwei china ((chang tan) OR (chang mae)) hong ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yao) or (ganga ya)) yang kwei china ((chang tan) OR (chang mae)) hong ghi ;*".
