Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
cau luc » cau truc, cau phuc
cau xuc » cam xuc, cau truc, chat xuc
nang xa » nang x, lang xa, nang ma
sach v » sach va, sach y, sach vay
sach 2 » sach y
di cua » dai cua, doi cua, de 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: tu ((sach v) OR (sach 2)) nang xa hoi. hieu van ((cau xuc) OR (cau luc)) va hanh di cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach v) OR (sach 2)) nang xa hoi. hieu van ((cau xuc) or (cau luc)) va hanh di cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach v) OR (sach 2)) nang xa hoi. hieu van ((cau xuc) or (cau luc)) va hanh di cua triet*.
