Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
chiet tach » chieu sach
canh doanh » hanh doanh, chinh doanh, doanh doanh
cong doan » cong dan, cong hoan, dong doanh
cua hang » cua nhung, cua cong, cua ban
cua dang » cua cong, cua ban
doan van » doan va, hoang van, luan van

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) OR (chiet tach)) - canh doanh ((cua hang) OR (cua dang)) cong doan van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chiet tach)) - canh doanh ((cua hang) OR (cua dang)) cong doan van ban~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chiet tach)) - canh doanh ((cua hang) OR (cua dang)) cong doan van ban*.
