• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien nhanh) OR (thien thanh)) - manh ((trung ca) OR (trung cap)) thuong cong van than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien nhanh) or (thien thanh)) - manh ((trung ca) OR (trung cap)) thuong cong van than cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien nhanh) or (thien thanh)) - manh ((trung ca) OR (trung cap)) thuong cong van than cau*.
