Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
so sach » so sanh, bo sach, co sach
sach ky » sac ky, sach y, sach ty
van hoi » van hoc, van hoe, van loi
hieu va » lieu va, hieu qua
cac xuc » cam xuc, cac nuoc, chat xuc
va hanh » van hanh, va thanh, va danh
xuc va » duc va, tuc va, luc va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ky nang ((van hoi) or (van hoa)). hieu va cac xuc va hanh vi ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky nang ((van hoi) OR (van hoa)). hieu va cac xuc va hanh vi ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky nang ((van hoi) or (van hoa)). hieu va cac xuc va hanh vi ((cua triet) OR (su triet))*".
