Perhaps you should try some spelling variations:
thanh luan » tranh luan, thanh xuan, thanh tuan
dang cong » dung cong
hien anh » hien hanh, thien anh, tien anh
dien anh » dien dan
van dang » van dong, van dung, van nang
cong dan » cong san, cong tan, huong dan
dan chan » dan gian, dan ca, van chat
chan cao » chan cho, chat cao, chay cao

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 ((hien anh) OR (((dien anh) OR (tieng anh)))) - thanh luan van dang cong dan chan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien anh) or (((dien anh) OR (tieng anh)))) - thanh luan van dang cong dan chan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien anh) or (((dien anh) OR (tieng anh)))) - thanh luan van dang cong dan chan cao*.
