Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
anh dung » anh huong, sach dung, ung dung
anh dong » anh huong, anh son
cua bang » chua bang, cua ban, cua dang
cong san » cong tac
cong tan » cong tac, cong thanh, cong ty

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