• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu tinh)) - canh tranh cua thong cong san ((chan cau) OR (chinh cau))~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu tinh)) - canh tranh cua thong cong san ((chan cau) OR (chinh cau))*.
