Perhaps you should try some spelling variations:
te sach » toc sach
va danh » va dinh, va dan, dia danh
va hanh » van hanh, va thanh, ban hanh
hieu va » lieu va, hieu qua
cua tre » cua te, cuu tre, cua triet
nang xa » lang xa, nang ma, mang xa
sach v » sach va, sach y, sach 2
vi cua » vai cua, di cua
va cam » va cham, va cac, va cao

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 v ((nang xa) or (nang x)) hoi. hieu va cam xuc ((va hanh) OR (va danh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach v ((nang xa) OR (nang x)) hoi. hieu va cam xuc ((va hanh) OR (va danh)) vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v ((nang xa) or (nang x)) hoi. hieu va cam xuc ((va hanh) OR (va danh)) vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach v ((nang xa) or (nang x)) hoi. hieu va cam xuc ((va hanh) OR (va danh)) vi cua tre*.
