Perhaps you should try some spelling variations:
chinh doanh » kinh doanh
chieu sach » chinh sach, chiet tach, chieu sang
hanh doanh » hang doanh, doanh doanh, kinh doanh
dong trong » duong trong, dung trong, cong trong
hoc chieu » hoc thieu, ho chieu, hoc hien
chua dong » cua dong, ha dong, huy dong
doan van » doan va, hoang van, luan van
dan van » dang van, dao van, tan van

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 sach - ((hanh doanh) OR (chinh doanh)) chua dong trong ((dan van) OR (doan van)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu sach - ((hanh doanh) OR (chinh doanh)) chua dong trong ((dan van) or (doan van)) ban~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu sach - ((hanh doanh) OR (chinh doanh)) chua dong trong ((dan van) or (doan van)) ban*.
