Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
doc sach » hoc sach, nuoc sach, dac sac
toc sach » hoc sach, thuoc sach, nuoc sach
qua cam » qua cham, qua cac, qua ca
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua

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: ((doc sach) OR (toc sach)) y nang ((xa hoi) OR (cac khoan)). hieu qua cam xuc va danh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc sach) OR (toc sach)) y nang ((xa hoi) or (cac khoan)). hieu qua cam xuc va danh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((doc sach) OR (toc sach)) y nang ((xa hoi) or (cac khoan)). hieu qua cam xuc va danh vi cua triet*.
