Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
dinh lai » dinh lam, dinh lap, dinh tai
van dinh » van minh, van dich, va dinh
chat xuc » chat huu, cam xuc, chao xu
cham xuc » cam xuc, cham soc, pham duc
lang van » dang van, tang van, hoang van
hieu ve » hieu va, hieu van
lang ha » long ha
lai cua » dai cua, hai cua, lai chau
cua tre » cua te, cuu tre, cua triet

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: toc sach y ((lang van) OR (lang ha)) hoi. hieu ve ((cham xuc) OR (chat xuc)) van dinh lai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y ((lang van) or (lang ha)) hoi. hieu ve ((cham xuc) OR (chat xuc)) van dinh lai cua tre~".
• Adding a wildcard symbol may retrieve word variants: toc sach y ((lang van) or (lang ha)) hoi. hieu ve ((cham xuc) OR (chat xuc)) van dinh lai cua tre*.
