Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
canh trong » anh trong, hanh trong, lanh trong
kieu tinh » lieu tinh, trieu tinh, diep tinh
trong hat » trong hoat, trong phat, trong nhat
trong qua » trong quan, thong qua, trong nha
hat dung » vat dung, dat dung, hai dung
qua than » qua thanh, qua phan, qua tan
than cap » khan cap, thanh lap, thanh cac

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: doc ((chieu tinh) OR (kieu tinh)) - canh trong hat dung trong qua than cap~.
• Adding a wildcard symbol may retrieve word variants: doc ((chieu tinh) or (kieu tinh)) - canh trong hat dung trong qua than cap*.
