Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu sach » chinh sach, chiet tach, chieu sang
hanh doanh » hang doanh, chinh doanh, doanh doanh
van thanh » ban thanh, van tuan
bang cong » dang cong, bang song, hang cong
cua bang » chua bang, cua ban, cua dang
cong tac » cong ty
nhan tap » nhan tai, han tap, phan tap
nhan tao » nhan tai, nhan dan

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 sach - ((hanh doanh) OR (van thanh)) cua bang cong tac ((nhan tap) OR (nhan tao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - ((hanh doanh) or (van thanh)) cua bang cong tac ((nhan tap) OR (nhan tao))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((hanh doanh) or (van thanh)) cua bang cong tac ((nhan tap) OR (nhan tao))*.
