• If you are trying to use Boolean operators, they must be ALL CAPS: hoc tinh sach - manh ((trung vap) OR (trung va)) nhung phuong ban ((thanh cau) OR (thanh mau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc tinh sach - manh ((trung vap) or (trung va)) nhung phuong ban ((thanh cau) OR (thanh mau))*".
