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
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
sach v » sach va, sach y, sach vay
va cam » va cham, va cac, va cao
sach 2 » sach y

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 v) OR (sach 2)) 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 v) OR (sach 2)) 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 v) OR (sach 2)) lang xa hoi. hieu va cam xuc ban ((hang vi) or (hanh vi)) cua triet*.
