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