Perhaps you should try some spelling variations:
chieu sang » chieu xanh, hieu lang, nhieu tang
chieu sach » chinh sach, chiet tach, chieu xanh
nhung cong » dung cong, thong cong, hang cong
chinh ta » chinh tai, chinh va, chinh tri
ta nhung » tay nhung, va nhung, tu nhung
cong san » cong tac
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac

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 sang) OR (chieu sach)) - hanh chinh ta nhung cong san ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) OR (chieu sach)) - hanh chinh ta nhung cong san ((than cau) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) OR (chieu sach)) - hanh chinh ta nhung cong san ((than cau) or (than cap))*.
