Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
doi chieu » doc hieu, doi chi, ho chieu
doanh cua » doanh luan
cong cong » cong dong, trong cong, dung cong
cong sang » cong san, cong lang, cong vang
ban cua » ban quan
tao cau » tao cu, tao cao, tao cac

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 sach - canh ((doanh cua) OR (ban cua)) cong cong sang ((tao cau) OR (tao sau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - canh ((doanh cua) or (ban cua)) cong cong sang ((tao cau) OR (tao sau))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - canh ((doanh cua) or (ban cua)) cong cong sang ((tao cau) OR (tao sau))*.
