Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, truong thanh
hoc thiet » hoc thieu, hoc thuyet, hoc hien
tranh van » tran van, trinh van, thanh van
ho chieu » theo chieu, hoc thieu, doi chieu
van dung » van dong, xay dung, tin dung
cong tan » cong tac, cong san, cong ty
toan cau » toan cao, toan ban, toan tap

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