• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hieu manh) OR (nghiep nganh)) - nhanh mang qua dung phong ban ((thanh chau) OR (thanh cha))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) or (nghiep nganh)) - nhanh mang qua dung phong ban ((thanh chau) OR (thanh cha))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (nghiep nganh)) - nhanh mang qua dung phong ban ((thanh chau) OR (thanh cha))*.
