• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chau) OR (theo phap)) tinh - anh bang luan ((bang cong) OR (hang cong)) dan can cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chau) OR (theo phap)) tinh - anh bang luan ((bang cong) or (hang cong)) dan can cau".
• Adding a wildcard symbol may retrieve word variants: ((theo chau) OR (theo phap)) tinh - anh bang luan ((bang cong) or (hang cong)) dan can cau*.
