• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - ((canh trinh) OR (canh tinh)) van nhuong cong doan phan tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - ((canh trinh) OR (canh tinh)) van nhuong cong doan phan tu*".
