Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh trang » thanh trung, canh tranh, hanh trinh
hoc chieu » hoc thieu, ho chieu, hoc hien
dan dung » van dung, tin dung
cong tac » cong ty
tac than » tac thanh, tam than, tac nhan
than cau » toan cau, phan cau, than cap
ap dung » van dung

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - hanh trang ((((ap dung) OR (xay dung))) OR (dan dung)) cong tac than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - hanh trang ((((ap dung) OR (xay dung))) or (dan dung)) cong tac than cau~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - hanh trang ((((ap dung) OR (xay dung))) or (dan dung)) cong tac than cau*.
