Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
so sach » so sanh, bo sach, co sach
va tham » van tham, va thanh, va thuat
va cham » va chat
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
y sang » duy sang
_ sang » _ san
ma hoi » mai hoi, xa hoi, ma hoa
soc va » hoc va, loc va, doc 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: so sach ((y sang) OR (_ sang)) ma hoi. lieu ((va tham) OR (va cham)) soc va danh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ((y sang) OR (_ sang)) ma hoi. lieu ((va tham) or (va cham)) soc va danh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: so sach ((y sang) OR (_ sang)) ma hoi. lieu ((va tham) or (va cham)) soc va danh vi cua triet*.
