Perhaps you should try some spelling variations:
te sach » toc sach
sach uu » sach luu, sach tu, sach xu
hanh ve » hanh vi, hanh va, hanh kem
xuc van » duc van, luc van, vuc van
cao xuc » cam xuc, cao duc, cao suc
hieu va » hieu qua
nang xa » nang x, lang xa, nang ma
uu nang » cuu nang, vu nang, cuu nong
su hien » su kien, su tien, thu hien
anh ve » anh va, anh viet, thanh ve

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach uu nang xa hoi. ((hieu va) OR (lieu va)) cao xuc van ((anh ve) or (hanh ve)) su hien~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach uu nang xa hoi. ((hieu va) OR (lieu va)) cao xuc van ((anh ve) OR (hanh ve)) su hien.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach uu nang xa hoi. ((hieu va) OR (lieu va)) cao xuc van ((anh ve) or (hanh ve)) su hien".
• Adding a wildcard symbol may retrieve word variants: te sach uu nang xa hoi. ((hieu va) OR (lieu va)) cao xuc van ((anh ve) or (hanh ve)) su hien*.
