Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
doi chieu » doc hieu, doi chi, ho chieu
bang luan » tang luan, hang luan, dung luan
luan hung » luan chung, lan hung, luan ung
anh bang » anh hoang, anh quang, tinh bang
cong dan » cong san, cong tan, cong dong
toan ban » van 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 sach - anh bang luan hung ((cong dan) OR (huong dan)) ((toan tap) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - anh bang luan hung ((cong dan) or (huong dan)) ((toan tap) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - anh bang luan hung ((cong dan) or (huong dan)) ((toan tap) OR (toan ban))*.
