Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hanh doanh » chinh doanh, doanh doanh, kinh doanh
hang doanh » nhung doanh, van doanh, dung doanh
dong cong » duong cong, dung cong, dang cong
ho chieu » theo chieu, hoc thieu, doi chieu
cua dong » chua dong, cua cong, cua dang
san tran » ban tran, dang tran, san trung

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 sach - ((hanh doanh) OR (hang doanh)) cua dong cong ((san tran) OR (tan tran)) tuan~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((hanh doanh) or (hang doanh)) cua dong cong ((san tran) OR (tan tran)) tuan~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((hanh doanh) or (hang doanh)) cua dong cong ((san tran) OR (tan tran)) tuan*.
