• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (hien nhanh)) - ((hanh trung) OR (thanh trung)) tuan phong cong anh tuan bang*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (hien nhanh)) - ((hanh trung) or (thanh trung)) tuan phong cong anh tuan bang*".
