Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
dung doi » huong doi, dung tai, dung co
so sach » so sanh, bo sach, co sach
doi cua » dai cua, hoi cua
xa dung » xay dung, xa dong, va dung
cua tre » cua te, cuu tre, cua triet
sach ky » sac ky, sach y, sach ty
hieu ve » hieu va
lang xa » lang ha, dang xay, lang van
nang xa » nang x, nang ma, mang xa
xuc xa » tuc xa, buc xa

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: so sach ky ((nang xa) OR (lang xa)) hoi. ((hieu ve) OR (hieu van)) cam xuc xa dung doi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky ((nang xa) OR (lang xa)) hoi. ((hieu ve) or (hieu van)) cam xuc xa dung doi cua tre~".
• Adding a wildcard symbol may retrieve word variants: so sach ky ((nang xa) OR (lang xa)) hoi. ((hieu ve) or (hieu van)) cam xuc xa dung doi cua tre*.
