Perhaps you should try some spelling variations:
chiet tach » chieu sach
thanh tung » thanh cong
cua nhung » va nhung
tung cua » trung cua, tuong cua, dung cua
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
than cau » toan cau, phan cau, than cap

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 ((chiet tach) OR (chinh sach)) - thanh tung cua nhung ((cong dan) OR (cong tan)) than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chiet tach) or (chinh sach)) - thanh tung cua nhung ((cong dan) OR (cong tan)) than cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chiet tach) or (chinh sach)) - thanh tung cua nhung ((cong dan) OR (cong tan)) than cau*.
