Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hanh tang » hanh trang, anh tang, hanh mang
cua nhung » va nhung
ho chieu » theo chieu, hoc thieu, doi chieu
tang cua » mang cua, hang cua, tang luan
cong dan » cong tan, huong dan, cong tac
cong san » cong tac
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: ho chieu sach - hanh tang cua nhung ((((cong dan) OR (cong dong))) OR (cong san)) toan cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh tang cua nhung ((((cong dan) or (cong dong))) or (cong san)) toan cau*.
