• If you are trying to use Boolean operators, they must be ALL CAPS: vu sai ky tang ((van hoi) OR (van hoc)). hieu ve cam xuc ((va dang) OR (hoa lang)) de cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sai ky tang ((van hoi) OR (van hoc)). hieu ve cam xuc ((va dang) or (hoa lang)) de cua tre".
