hanh trinh » canh tranh, hanh chinh
trinh quan » tinh quang, trinh luat, trinh han
quan thong » quang thong, quan trong, xuan thong
cong tinh » cong vinh, long tinh, cong thanh

• If you are trying to use Boolean operators, they must be ALL CAPS: ((chao chieu) OR (cao hieu)) xanh - hanh trinh quan thong ((cong tinh) OR (cong trinh)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((chao chieu) or (cao hieu)) xanh - hanh trinh quan thong ((cong tinh) OR (cong trinh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((chao chieu) or (cao hieu)) xanh - hanh trinh quan thong ((cong tinh) OR (cong trinh)) toan cau*.
