• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu tinh)) - hanh trung cua ((khong cong) OR (chong cong)) van tan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu tinh)) - hanh trung cua ((khong cong) OR (chong cong)) van tan tap".
