Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
doi chieu » doc hieu, doi chi, ho chieu
thang cua » thong cua, hang cua, than cua
tranh cua » doanh cua, manh cua
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
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 - hanh ((thang cua) OR (tranh cua)) nhung ((cong dan) OR (cong tan)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - hanh ((thang cua) or (tranh cua)) nhung ((cong dan) OR (cong tan)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - hanh ((thang cua) or (tranh cua)) nhung ((cong dan) OR (cong tan)) toan ban*.
