• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (hien nhanh)) - hanh trung cua nhung huong ((dan than) OR (dan chan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (hien nhanh)) - hanh trung cua nhung huong ((dan than) or (dan chan)) cao".
