Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hang vi » hang va, hang di, khang voi
xuc ban » duc ban, cuc ban, quoc ban
vu sach » vu bach, vu khach
lang xa » lang ha, dang xay, lang van
su sach » so sach
hieu va » lieu va, hieu qua
v lang » va lang, o lang, _ lang
va cam » va cham, va cac, va cao

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: ((vu sach) OR (su sach)) v lang xa hoi. hieu va cam xuc ban ((hang vi) OR (hanh vi)) cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (su sach)) v lang xa hoi. hieu va cam xuc ban ((hang vi) or (hanh vi)) cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) OR (su sach)) v lang xa hoi. hieu va cam xuc ban ((hang vi) or (hanh vi)) cua triet*.
