Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
thien van » thi van
su triet » su viet, su tien, ve triet
dam thuc » am thuc, dan thuc, nam thuc
van anh » van thanh, tuan anh, van minh
so sach » so sanh, bo sach, co sach
sach ky » sac ky, sach y, sach ty
tang xa » trang xa, tang ma, lang xa
ky tang » ky nang, ky dang, kho tang
anh vi » hanh vi, anh va, anh ve

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ky tang xa hoi. thien van ((dam thuc) or (cam xuc)) van anh vi ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky tang xa hoi. thien van ((dam thuc) OR (cam xuc)) van anh vi ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky tang xa hoi. thien van ((dam thuc) or (cam xuc)) van anh vi ((cua triet) OR (su triet))*".
