Perhaps you should try some spelling variations:
doc sach » hoc sach, toc sach, nuoc sach
sach dao » lanh dao
van danh » van doanh, van anh, van hanh
phat xuc » chat xuc, phat xuat, phap xu
danh du » danh dau, danh tu, dinh du
xuc van » duc van, luc van, vuc van
hieu va » hieu qua
hang xa » hoang xa, hang ca, lang xa
cua tre » cua te, cuu tre, cua triet
du cua » duy cua, dau cua, dum 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: doc sach dao ((hang xa) OR (hang va)) hoi. ((hieu va) OR (lieu va)) phat xuc van danh du cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc sach dao ((hang xa) OR (hang va)) hoi. ((hieu va) or (lieu va)) phat xuc van danh du cua tre~".
• Adding a wildcard symbol may retrieve word variants: doc sach dao ((hang xa) OR (hang va)) hoi. ((hieu va) or (lieu va)) phat xuc van danh du cua tre*.
