nhanh tinh » nhanh thanh, nhan sinh
hanh trinh » canh tranh, hanh chinh

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - ((thanh tinh) OR (((nhanh tinh) OR (hanh trinh)))) cua cong nong san toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - ((thanh tinh) or (((nhanh tinh) OR (hanh trinh)))) cua cong nong san toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((thanh tinh) or (((nhanh tinh) OR (hanh trinh)))) cua cong nong san toan tap*.
