Perhaps you should try some spelling variations:
cau triet » cau trieu, su triet, cua triet
va thanh » gia thanh, ban thanh, le thanh
thu sach » thuat sach, thuoc sach, thu hoach
va tinh » may tinh
tu sach » su sach, te sach, tu cach
nang xa » nang x, lang xa, nang ma
lam xuc » cam xuc, lam duoc
va lam » van lam, va lap
di cau » da cau, diem cau

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thu sach)) ky nang xa hoi. lieu va lam xuc ((va thanh) OR (va tinh)) di cau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ky nang xa hoi. lieu va lam xuc ((va thanh) OR (va tinh)) di cau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ky nang xa hoi. lieu va lam xuc ((va thanh) OR (va tinh)) di cau triet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) ky nang xa hoi. lieu va lam xuc ((va thanh) OR (va tinh)) di cau triet*.
