• If you are trying to use Boolean operators, they must be ALL CAPS: te sach v nang ((ma hoi) OR (mai hoi)). hieu va pham duy ((va thanh) OR (gia thanh)) phan cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang ((ma hoi) or (mai hoi)). hieu va pham duy ((va thanh) OR (gia thanh)) phan cua tre".
