• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky ((tang ma) OR (mang may)) hoi. hieu ((va cam) OR (va cham)) duc danh thanh nhan cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky ((tang ma) OR (mang may)) hoi. hieu ((va cam) or (va cham)) duc danh thanh nhan cua tre".
• Adding a wildcard symbol may retrieve word variants: su sai ky ((tang ma) OR (mang may)) hoi. hieu ((va cam) or (va cham)) duc danh thanh nhan cua tre*.
