Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
thu sach » tu sach, thuat sach, thuoc sach
va thanh » gia thanh, ban thanh, va tinh
va triet » va thiet, va trien, ve triet
cau xuc » cam xuc, cau luc, cau truc
sach ky » sac ky, sach y, sach ty
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
va hanh » van hanh, va danh, ban hanh
va cau » van cau, va cac, va dau

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 nang xa hoi. hieu va cau xuc ((va hanh) OR (va thanh)) de ((cua triet) OR (va triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky nang xa hoi. hieu va cau xuc ((va hanh) or (va thanh)) de ((cua triet) OR (va triet))~".
• Adding a wildcard symbol may retrieve word variants: thu sach ky nang xa hoi. hieu va cau xuc ((va hanh) or (va thanh)) de ((cua triet) OR (va triet))*.
