• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (hoc thieu)) xanh - thanh trung ((toan thong) OR (tran phong)) cong dan phan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) OR (hoc thieu)) xanh - thanh trung ((toan thong) or (tran phong)) cong dan phan cau*".
