• If you are trying to use Boolean operators, they must be ALL CAPS: wan wang ((tan hua) OR (tuan hua)) (rent OR (rest OR test)) ((yang jin) OR (ying jin)) won sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan wang ((tan hua) OR (tuan hua)) (rent or (rest or test)) ((yang jin) or (ying jin)) won sau ;*".
