Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
truong cua » truong ca, truong quan, huong cua
truong cao » truong dai
doi chieu » doc hieu, doi chi, ho chieu
dung cong » dung trong
cong ban » cong bang, cong san, cong tan
than cau » toan cau, than cap, thanh chau
phan cau » phan dau, phan cac, phan tu

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 - thanh ((truong cua) OR (truong cao)) dung cong ban ((than cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - thanh ((truong cua) or (truong cao)) dung cong ban ((than cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - thanh ((truong cua) or (truong cao)) dung cong ban ((than cau) OR (phan cau))*.
