• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) or (thien thanh)) - canh manh cua dung chung han ((thanh chau) OR (thanh cha))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (thien thanh)) - canh manh cua dung chung han ((thanh chau) OR (thanh cha))*.
