Perhaps you should try some spelling variations:
hang khoa » dung khoa
minh doan » minh doanh, minh toan, minh don
ban hang » ngan hang
ket luan » te luan, dat luan, ket doan
tieu thi » trieu thi, tiep thi, tieu thu
thi minh » chi minh, thi hanh, thi bich
doan hoc » toan hoc, dan hoc, doan phuoc
hien » bien, vien, hieu

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: "ban hang khoa luan ((ket luan) OR (ket qua)) tieu thi minh doan hoc hien~".
• Adding a wildcard symbol may retrieve word variants: ban hang khoa luan ((ket luan) OR (ket qua)) tieu thi minh doan hoc hien*.
