Perhaps you should try some spelling variations:
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu van
hieu va » lieu va, hieu qua
cua tre » cua te, cuu tre, cua triet
sach v » sach va, sach y, sach 2
v nang » va nang, vu nang, van nang
xuc va » tuc va, luc va, xac va
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 v nang xa hoi. ((hieu ve) OR (hieu va)) cam ((xuc va) OR (duc va)) hanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang xa hoi. ((hieu ve) OR (hieu va)) cam ((xuc va) or (duc va)) hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach v nang xa hoi. ((hieu ve) OR (hieu va)) cam ((xuc va) or (duc va)) hanh vi cua tre*.
