• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sang)) - hanh trang cua ((khong cong) OR (thong cong)) van phan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu sang)) - hanh trang cua ((khong cong) OR (thong cong)) van phan cau*".
