Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tranh cua » manh cua
doanh cua » doanh luan
ho chinh » hoc chinh, cho chinh, hoa chinh
cong san » cong tac
than cap » khan cap, thanh lap, thanh cac
khoa cam » khoan cam, khoa kham, khoa ma

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 chinh sach - canh ((tranh cua) OR (doanh cua)) nhung cong san ((than cap) OR (khoa cam))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chinh sach - canh ((tranh cua) OR (doanh cua)) nhung cong san ((than cap) or (khoa cam))~".
• Adding a wildcard symbol may retrieve word variants: ho chinh sach - canh ((tranh cua) OR (doanh cua)) nhung cong san ((than cap) or (khoa cam))*.
