Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
hanh hai » thanh hai, nhanh hai, hang hai
cham xuc » cam xuc, chat xuc, cham soc
hieu ve » hieu va, hieu van
hai cua » thai cua, dai cua, hoi cua
va hanh » van hanh, va thanh, va danh
ve cham » va cham, ve chat, vu cham
ma hoi » mai hoi, xa hoi, ma hoa
xuc va » duc va, tuc va, luc va
y nang » ly nang, v nang, may nang
cua te » cua tu

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: ((te sach) OR (toc sach)) ((y nang) OR (ky nang)) ma hoi. hieu ve cham xuc va hanh hai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) ((y nang) or (ky nang)) ma hoi. hieu ve cham xuc va hanh hai cua te~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) ((y nang) or (ky nang)) ma hoi. hieu ve cham xuc va hanh hai cua te*.
