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