Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh doanh » hang doanh, chinh doanh, doanh doanh
doanh luan » doanh nhan
nhung cong » dung cong, hang cong, nhung don
thong cong » trong cong, tong cong, thong thong
dan phan » doan phan, dan chan, van phan

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chinh sach) or (chieu tinh)) - hanh doanh luan ((nhung cong) OR (thong cong)) dan phan tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chinh sach) OR (chieu tinh)) - hanh doanh luan ((nhung cong) OR (thong cong)) dan phan tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (chieu tinh)) - hanh doanh luan ((nhung cong) OR (thong cong)) dan phan tu".
• Adding a wildcard symbol may retrieve word variants: ho ((chinh sach) or (chieu tinh)) - hanh doanh luan ((nhung cong) OR (thong cong)) dan phan tu*.
