Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu tach » chiet tach, chieu sach, chiu trach
canh doanh » hanh doanh, chinh doanh, doanh doanh
nhung cong » dung cong, hang cong, nhung don
thong cong » trong cong, tong cong, thong thong
doanh va » doan va, doanh tai, doanh cua
san toan » van toan, manh toan, xuan toan
dan toan » van toan, dan than, manh toan

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 tach - canh doanh va ((nhung cong) OR (thong cong)) ((san toan) OR (dan toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tach - canh doanh va ((nhung cong) OR (thong cong)) ((san toan) or (dan toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu tach - canh doanh va ((nhung cong) OR (thong cong)) ((san toan) or (dan toan)) cau*.
