Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hang dien » quang dien, dang dieu, nhan dien
hieu van » hieu va, thien van, lieu va
cau xuc » cam xuc, cau luc, cau truc
tu sach » thu sach, su sach, te sach
van cau » van dau, van hau, van chat
nang xa » lang xa, nang ma, mang xa
sach v » sach va, sach y, sach 2
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 v ((nang xa) OR (nang x)) hoi. hieu van cau xuc va ((hang dien) OR (hanh vi)) cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach v ((nang xa) OR (nang x)) hoi. hieu van cau xuc va ((hang dien) or (hanh vi)) cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach v ((nang xa) OR (nang x)) hoi. hieu van cau xuc va ((hang dien) or (hanh vi)) cua triet*.
