Perhaps you should try some spelling variations:
doc sach » hoc sach, toc sach, nuoc sach
chat xuc » chat huu, cam xuc, chao xu
van chat » cao chat
sach thi » sach thu, sach tai, sach thieu
hieu van » hieu va, thien van, lieu va
hang ca » hang va, nang cao, hang tai
hang xa » hoang xa, hang va, lang xa
xuc van » duc van, luc van, vuc van
cua tre » cua te, cuu tre, cua triet
anh de » hanh de, anh ve, anh du

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: doc sach thi ((hang xa) OR (hang ca)) hoi. hieu van chat xuc van ((anh de) OR (anh d)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc sach thi ((hang xa) OR (hang ca)) hoi. hieu van chat xuc van ((anh de) or (anh d)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: doc sach thi ((hang xa) OR (hang ca)) hoi. hieu van chat xuc van ((anh de) or (anh d)) cua tre*.
