• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (doi chieu)) sach - hanh tranh cua thong cong dan ((than cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (doi chieu)) sach - hanh tranh cua thong cong dan ((than cau) OR (phan cau))*.
