Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
tranh van » tran van, trinh van, thanh van
dung cong » dung trong
ho chieu » hoc thieu, doi chieu, mot chieu
van dung » van dong, xay dung, tin dung
cong van » cong vang, cong san, song van
toan ban » van ban
phan cau » phan dau, phan cac, phan tu

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: ((ho chieu) OR (theo chieu)) tinh - canh tranh van dung cong van ((toan ban) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) tinh - canh tranh van dung cong van ((toan ban) or (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) tinh - canh tranh van dung cong van ((toan ban) or (phan cau))*.
