Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
cham xuc » cam xuc, chat xuc, cham soc
lang van » dang van, tang van, hoang van
dinh lap » dinh lam, trinh lap, dinh lang
dinh lai » dinh lam, dinh tai, dinh hai
xuc van » duc van, luc van, vuc van
ve cham » va cham, ve chat, vu cham
hieu ve » hieu va, hieu van
lang ha » long ha
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 van ((dinh lai) OR (dinh lap)) 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 van ((dinh lai) OR (dinh lap)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: toc sach y ((lang van) or (lang ha)) hoi. hieu ve cham xuc van ((dinh lai) OR (dinh lap)) cua tre*.
