Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thien van » thi van
danh vi » dinh vi, danh di, danh va
lam xuc » cam xuc, lam duoc
tu sach » thu sach, su sach, te sach
lang xa » lang ha, dang xay, lang van
mang xa » mang may, dang xay, mang cua
van lam » van nam
xuc va » duc va, tuc va, luc va

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: tu sach y ((mang xa) OR (lang xa)) hoi. thien van lam xuc va ((danh vi) OR (hanh vi)) cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((mang xa) or (lang xa)) hoi. thien van lam xuc va ((danh vi) OR (hanh vi)) cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach y ((mang xa) or (lang xa)) hoi. thien van lam xuc va ((danh vi) OR (hanh vi)) cua triet*.
