Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
luan trong » quan trong, luat trong, luan tuong
mot chieu » doi chieu, ho chieu
hanh dung » thanh dung, anh dung, hanh dong
cong tan » cong tac, cong san, cong thanh
toan cao » toan tap
toan ban » van ban

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: ((mot chieu) OR (theo chieu)) xanh - hanh dung luan trong cong tan ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (theo chieu)) xanh - hanh dung luan trong cong tan ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (theo chieu)) xanh - hanh dung luan trong cong tan ((toan cao) OR (toan ban))*.
