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