Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
thanh dung » thanh duong, thanh tung, thanh hung
hanh dung » anh dung, hanh dong, manh dung
ho chieu » hoc thieu, doi chieu, mot chieu
dung anh » dung danh, duong anh, dong anh
anh toan » manh toan, anh tuan, thanh toan
toan cau » toan cao, toan ban, toan tap
van ung » van dung, van hung, van sung

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 chieu) OR (ho chieu)) lang - ((hanh dung) OR (thanh dung)) van ung dung anh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (ho chieu)) lang - ((hanh dung) OR (thanh dung)) van ung dung anh toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (ho chieu)) lang - ((hanh dung) OR (thanh dung)) van ung dung anh toan cau*.
