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