Perhaps you should try some spelling variations:
hoc chieu » hoc thieu, hoc hien, hoc dieu
hanh tran » hanh trang, thanh tran, hanh tram
dung cong » dung trong
ho chieu » theo chieu, hoc thieu, doi chieu
tran van » luan van
van dung » van dong, xay dung, tin dung
ban than » ban thanh, van thanh, ban 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: ((hoc chieu) OR (ho chieu)) sang - hanh tran van dung cong ((xuan toan) OR (ban than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) OR (ho chieu)) sang - hanh tran van dung cong ((xuan toan) or (ban than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) OR (ho chieu)) sang - hanh tran van dung cong ((xuan toan) or (ban than)) cau*.
