Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
thanh va » thanh van, thanh ha, thanh ve
so sach » so sanh, bo sach, co sach
hanh va » hang va, hanh vi
xuc van » duc van, luc van, vuc van
tu cham » toc cham, thi cham
sach ky » sac ky, sach y, sach ty
hieu tu » chieu tu, hieu tuc, hien tu
hoa hoi » khoa hoi, hoa doi, hoc hoi
ky dong » ly dong, ky dang, ky cong
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: so sach ky dong ((hoa hoi) OR (hoa hoc)). hieu tu cham xuc van ((thanh va) OR (hanh va)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky dong ((hoa hoi) or (hoa hoc)). hieu tu cham xuc van ((thanh va) OR (hanh va)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: so sach ky dong ((hoa hoi) or (hoa hoc)). hieu tu cham xuc van ((thanh va) OR (hanh va)) cua tre*.
