Perhaps you should try some spelling variations:
chieu chien » thien chien, hieu hien
cua triet » cua viet, su triet
chien cac » hien cac, thien cac, chien cuoc
va triet » va thiet, va trien, ve triet
dinh vai » dinh van, dinh vi, dinh va
va dinh » van dinh, va kinh, va tinh
sach ky » sac ky, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
cac do » cac don, cac doi, cac du
do va » do van, so 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 ky) OR (sach y)) nang xa hoi. chieu chien cac do va dinh vai ((cua triet) OR (va triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) or (sach y)) nang xa hoi. chieu chien cac do va dinh vai ((cua triet) OR (va triet))~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) or (sach y)) nang xa hoi. chieu chien cac do va dinh vai ((cua triet) OR (va triet))*.
