Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh tung » thanh cong
dung cong » dung trong
thanh lap » thanh san, phan lap, thanh hai
cong van » cong vang, cong san, song van
than cap » khan cap, thanh cac, than cua
tung ap » tang ap, tung dan, tung bay
ap dung » xay dung, van dung

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: doi ((chieu xanh) OR (chieu tinh)) - thanh tung ap dung cong van ((than cap) OR (thanh lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu tinh)) - thanh tung ap dung cong van ((than cap) OR (thanh lap))~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu tinh)) - thanh tung ap dung cong van ((than cap) OR (thanh lap))*.
