Perhaps you should try some spelling variations:
chinh doanh » kinh doanh
tieu sach » chieu sach, dien sach, te sach
luan hang » luan nang, luan hung, luan tang
luan han » luan hoan, luan phan, luan van
cong tap » cuong tap, cong tan, tong tap
cong tac » cong ty
toan cau » toan cao, toan ban, toan tap

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: theo tieu sach - chinh doanh ((luan hang) OR (luan han)) ((cong tap) OR (cong tac)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu sach - chinh doanh ((luan hang) OR (luan han)) ((cong tap) or (cong tac)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo tieu sach - chinh doanh ((luan hang) OR (luan han)) ((cong tap) or (cong tac)) toan cau*.
