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