Perhaps you should try some spelling variations:
nhung cong » dung cong, hang cong, nhung don
chieu sach » chinh sach, chiet tach, chieu sang
thong cong » trong cong, tong cong, thong thong
hanh tran » hanh trang, thanh tran, hanh tram
ho chieu » theo chieu, hoc thieu, doi chieu
tran van » luan van
ban hang » ngan hang

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 tran van ((nhung cong) OR (thong cong)) ((xuan toan) OR (ban hang)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh tran van ((nhung cong) OR (thong cong)) ((xuan toan) or (ban hang)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh tran van ((nhung cong) OR (thong cong)) ((xuan toan) or (ban hang)) cau*.
