• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (hien hanh)) - hanh truong cua trong ((cong dao) OR (cuong dao)) van ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (hien hanh)) - hanh truong cua trong ((cong dao) OR (cuong dao)) van ban".
