Perhaps you should try some spelling variations:
thanh tung » thanh cong
hoc thieu » toc thieu, hoc hien
tung tham » tuong tham, tung pham, cung tham
tham dung » pham dung, tham cung, tham nhung
dung cong » dung trong
luan phan » luan van, luan hoan
ho chieu » theo chieu, doi chieu, mot chieu
van phan » van phong, van thanh, van ban

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) OR (hoc thieu)) sach - thanh tung tham dung cong ((van phan) OR (luan phan)) tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) sach - thanh tung tham dung cong ((van phan) or (luan phan)) tu~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) sach - thanh tung tham dung cong ((van phan) or (luan phan)) tu*.
