Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
sach ky » sach y, sach ty, sach kem
va hanh » van hanh, va danh, ban hanh
cao xuc » cam xuc, cao duc, cao suc
sac ky » cac ky, sai ky
va cao » va cac, va co, va dao
de cua » le cua, te cua, dieu 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: thu ((sach ky) OR (sac ky)) nang xa hoi. hieu va cao xuc ((va hanh) OR (va thanh)) de cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) or (sac ky)) nang xa hoi. hieu va cao xuc ((va hanh) OR (va thanh)) de cua triet~".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ky) or (sac ky)) nang xa hoi. hieu va cao xuc ((va hanh) OR (va thanh)) de cua triet*.
