• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky tang ((ma hoi) OR (xa hoi)). hieu ve cam duc tan thanh bac cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su xac)) ky tang ((ma hoi) OR (xa hoi)). hieu ve cam duc tan thanh bac cua tre*".
