Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hanh tranh » canh tranh, hanh trinh, hanh trang
doi chieu » doc hieu, doi chi, ho chieu
tranh cua » doanh cua, manh cua
cua trong » cua truong, cua trung, qua trong
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
toan cau » toan cao, toan ban, toan tap

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 - hanh tranh cua trong ((cong tan) OR (cong tac)) toan cau~.
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - hanh tranh cua trong ((cong tan) or (cong tac)) toan cau*.
