Perhaps you should try some spelling variations:
tinh huong » dinh huong
quang toan » quang tuan, quang tran, quang doan
kiem soat » kiem toan
hien luat » hieu luat, hieu suat
toan ban » van ban
ban kiem » bang kiem, van kiem, ban kem
van hien » van hieu, van tien

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( tinh quang toan ban kiem soat ) or ( ((tinh huong) OR (anh huong)) luan van hien luat ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tinh quang toan ban kiem soat ) OR ( ((tinh huong) OR (anh huong)) luan van hien luat )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh quang toan ban kiem soat ) or ( ((tinh huong) OR (anh huong)) luan van hien luat ))".
• Adding a wildcard symbol may retrieve word variants: (( tinh quang toan ban kiem soat ) or ( ((tinh huong) OR (anh huong)) luan van hien luat ))*.
