Perhaps you should try some spelling variations:
te sach » toc sach
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
va cam » va cham, va cac, va cao
vi cua » vai cua, di cua
x hoi » o hoi, x ho, 5 hoi

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 (xa hoi)). hieu va cam xuc ((va hanh) OR (va danh)) vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach y nang ((x hoi) or (xa hoi)). hieu va cam xuc ((va hanh) or (va danh)) vi cua tre*.
