Perhaps you should try some spelling variations:
hanh lai » hanh lam, hanh tai, thanh lap
dang xay » dang van, van xay
tu sach » thu sach, su sach, te sach
lai cuu » lai cua, lai chau, lai cuoc
hieu va » lieu va, hieu qua
cuu tre » cua tre, cau tren, cau treo
nang xa » nang x, lang xa, nang ma
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa
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: tu sach y ((nang xa) or (dang xay)) hoi. hieu va cam ((xuc va) OR (tuc va)) hanh lai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((nang xa) OR (dang xay)) hoi. hieu va cam ((xuc va) OR (tuc va)) hanh lai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((nang xa) or (dang xay)) hoi. hieu va cam ((xuc va) OR (tuc va)) hanh lai cuu tre*".
