Perhaps you should try some spelling variations:
thanh tra » thanh toan, thanh hoa
te sach » toc sach
qua cam » qua cham, qua cac, qua ca
tra cuu » tra cau, trau cua, trua cua
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, ly nang, v nang
luc va » duc va, tuc va, loc va
x hoi » xa hoi, x ho, 5 hoi
o hoi » co hoi, o hoc, o hai

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 y nang ((x hoi) OR (o hoi)). hieu qua cam ((tuc xa) OR (luc va)) thanh tra cuu tre~.
• Adding a wildcard symbol may retrieve word variants: te sach y nang ((x hoi) or (o hoi)). hieu qua cam ((tuc xa) or (luc va)) thanh tra cuu tre*.
