Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
mot chieu » doi chieu, ho chieu
hanh dung » thanh dung, anh dung, hanh dong
manh toan » thanh toan, anh tuan, tinh toan
dung van » duong van, dung va, dang van
anh toan » anh tuan, thanh toan, nganh toan
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 (mot chieu)) lang - hanh dung van ung dung ((anh toan) OR (manh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (mot chieu)) lang - hanh dung van ung dung ((anh toan) OR (manh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (mot chieu)) lang - hanh dung van ung dung ((anh toan) OR (manh toan)) cau*.
