Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
doanh luan » doanh nhan
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, ho chieu
cong san » cong tac
toan cau » toan cao, toan ban, toan tai
toan tap » toan 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: doi chieu xanh - canh ((doanh cua) OR (doanh luan)) nhung cong san ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - canh ((doanh cua) or (doanh luan)) nhung cong san ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - canh ((doanh cua) or (doanh luan)) nhung cong san ((toan cau) OR (toan tap))*.
