• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (nhieu tang)) - thanh trung quan nhung cong san ((than cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (nhieu tang)) - thanh trung quan nhung cong san ((than cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (nhieu tang)) - thanh trung quan nhung cong san ((than cau) OR (phan cau))*.
