• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu tinh)) - hanh tang cua tong cong tan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu tinh)) - hanh tang cua tong cong tan ((toan cau) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu tinh)) - hanh tang cua tong cong tan ((toan cau) or (toan ban))*.
