Perhaps you should try some spelling variations:
hien tranh » chien tranh, hien trang, thien thanh
kiem soat » kiem toan
quang uan » quang tuan, quang tran, quang chan
quang ban » quang binh, quang tuan, quang tran
van kiem » va kiem, van kien, van hieu
van hien » van hieu, van tien
luan » quan, lan

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

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