• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (hien nhanh)) - ((canh doanh) OR (hanh doanh)) cua dung hong van quan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (hien nhanh)) - ((canh doanh) or (hanh doanh)) cua dung hong van quan cau*".
