• If you are trying to use Boolean operators, they must be ALL CAPS: tu can ky sang ((lai hoi) OR (dai hoi)). hieu ((su chat) OR (soat chat)) duc va thanh phan cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu can ky sang ((lai hoi) OR (dai hoi)). hieu ((su chat) or (soat chat)) duc va thanh phan cua te~".
• Adding a wildcard symbol may retrieve word variants: tu can ky sang ((lai hoi) OR (dai hoi)). hieu ((su chat) or (soat chat)) duc va thanh phan cua te*.
