• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chi xanh) OR (chi anh)) - thanh trung qua dung cong dan ((thanh bac) OR (nhanh bac)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi xanh) or (chi anh)) - thanh trung qua dung cong dan ((thanh bac) OR (nhanh bac))".
• Adding a wildcard symbol may retrieve word variants: doi ((chi xanh) or (chi anh)) - thanh trung qua dung cong dan ((thanh bac) OR (nhanh bac))*.
