Perhaps you should try some spelling variations:
triet tinh » trieu tinh, trien tinh, trien kinh
canh doanh » hanh doanh, chinh doanh, doanh doanh
doanh luan » doanh nhan
mao triet » tao thiet, va triet, bo triet
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "mao triet tinh - canh doanh luan van ((cong dan) OR (cong san)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: mao triet tinh - canh doanh luan van ((cong dan) OR (cong san)) toan cau*.
