hanh trang » thanh trung, canh tranh, hanh trinh
trang cua » tranh cua, tang cua, trung cua

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - hanh trang cua nang song ((((doan phan) OR (dan phan))) OR (toan phan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - hanh trang cua nang song ((((doan phan) OR (dan phan))) or (toan phan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - hanh trang cua nang song ((((doan phan) OR (dan phan))) or (toan phan)) cau*.
