Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
canh bang » can bang, anh bang, lanh bang
ho chieu » theo chieu, hoc thieu, doi chieu
bang vat » bang va, dang vat, cang vat
vat dung » van dung, va dung, viet dung
cong dan » huong dan, cong dong, cong tac
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac

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: ho chieu xanh - canh bang vat dung ((((cong dan) OR (cong tan))) OR (cong san)) van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - canh bang vat dung ((((cong dan) OR (cong tan))) or (cong san)) van ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - canh bang vat dung ((((cong dan) OR (cong tan))) or (cong san)) van ban*.
