• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc hieu) OR (doc hieu)) nganh - thanh trung cuc phuong cong san ((phan cac) OR (phan dau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hieu) or (doc hieu)) nganh - thanh trung cuc phuong cong san ((phan cac) OR (phan dau))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc hieu) or (doc hieu)) nganh - thanh trung cuc phuong cong san ((phan cac) OR (phan dau))*.
