• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - thanh truong hoa khong ((cuong bang) OR (cong bang)) ((thanh chau) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - thanh truong hoa khong ((cuong bang) OR (cong bang)) ((thanh chau) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - thanh truong hoa khong ((cuong bang) OR (cong bang)) ((thanh chau) or (toan cao))*.
