Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
doanh hoan » doanh doanh, doanh khoa, doanh nhan
hang cong » dang cong, hang nong, bang cong
hoan va » khoan va, hoang va, doan va
va hang » van hang, va nang, va lang
san van » tan van, tran van, dang van
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 xanh) OR (chieu tinh)) - doanh hoan va hang cong ((san van) OR (luan van)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu tinh)) - doanh hoan va hang cong ((san van) OR (luan van)) ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu tinh)) - doanh hoan va hang cong ((san van) OR (luan van)) ban*.
