Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
vai cua » dai cua, hai cua, lai cua
hieu va » lieu va, hieu qua
va tham » van tham, va cham, va thanh
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
sach v » sach va, sach y, sach vay
xuc va » duc va, tuc va, luc va
loc va » hoc va, luc va
sach 2 » sach y

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach v) OR (sach 2)) nang xa hoi. hieu va tham ((xuc va) or (loc va)) hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach v) OR (sach 2)) nang xa hoi. hieu va tham ((xuc va) OR (loc va)) hanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach v) OR (sach 2)) nang xa hoi. hieu va tham ((xuc va) or (loc va)) hanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sach v) OR (sach 2)) nang xa hoi. hieu va tham ((xuc va) or (loc va)) hanh vai cua tre*.
