Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hanh doanh » hang doanh, chinh doanh, doanh doanh
doanh cua » doanh luan
trong tap » trong thap, trong tan, trong tai
ho chieu » theo chieu, hoc thieu, mot chieu
cua dung » cua dang, cua dong, qua dung
tong tap » tuong tac, trong tan, cong tac
doan ban » doanh ban, toan ban, doan van

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh doanh cua dung ((trong tap) OR (tong tap)) doan ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh doanh cua dung ((trong tap) OR (tong tap)) doan ban*.
