Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
hanh dung » thanh dung, hanh dong, manh dung
ho chieu » theo chieu, hoc thieu, doi chieu
anh dung » anh dong, anh huong, sach dung
van nong » van dong, van nang, van cong
nong dan » cong dan, nong san, nguong dan
chan cau » can cau, chinh cau, nhanh cau
phan cau » phan dau, phan cac, phan tu
luan » quan, lan

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 tinh - ((hanh dung) OR (anh dung)) luan van nong dan ((chan cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - ((hanh dung) or (anh dung)) luan van nong dan ((chan cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - ((hanh dung) or (anh dung)) luan van nong dan ((chan cau) OR (phan cau))*.
