Perhaps you should try some spelling variations:
te sach » toc sach
sach xa » sach dao, sach nha, sach bai
danh vi » hanh vi, dinh vi, danh di
hieu va » lieu va, hieu qua
hieu ve » hieu van
lang xa » lang ha, dang xay, lang van
xa lang » va lang, ba lang, ha lang
cua tre » cua te, cuu tre, cua triet
vi cua » vai cua, di cua

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: te sach xa lang xa hoi. ((hieu ve) OR (hieu va)) cham ((duc va) OR (tuc xa)) danh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach xa lang xa hoi. ((hieu ve) OR (hieu va)) cham ((duc va) or (tuc xa)) danh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach xa lang xa hoi. ((hieu ve) OR (hieu va)) cham ((duc va) or (tuc xa)) danh vi cua tre*.
