Perhaps you should try some spelling variations:
chinh doanh » kinh doanh
hieu nganh » vien nganh, hiem ngan, nghiep nganh
canh doanh » hanh doanh, doanh doanh, kinh doanh
hieu manh » chieu xanh, dieu hanh, hien hanh
dung cong » dung trong
cong luan » tong luan, cong tuan, dong luan
luan phan » luan van, luan hoan
phan dau » phan tu, hang dau
va dung » van dung, va duong, vat dung

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: hoc ((hieu manh) OR (hieu nganh)) - ((canh doanh) OR (chinh doanh)) va dung cong luan phan dau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hieu manh) OR (hieu nganh)) - ((canh doanh) or (chinh doanh)) va dung cong luan phan dau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) OR (hieu nganh)) - ((canh doanh) or (chinh doanh)) va dung cong luan phan dau*.
