Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
cua triet » su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
phan dau » phan tu, hang dau
cua viet » ca viet, hoa viet, cua vat
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
van dau » van dao

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 ky tang xa hoi. thi ((van dau) OR (phan dau)) tu va thanh lai ((cua triet) or (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky tang xa hoi. thi ((van dau) OR (phan dau)) tu va thanh lai ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky tang xa hoi. thi ((van dau) OR (phan dau)) tu va thanh lai ((cua triet) or (cua viet))".
• Adding a wildcard symbol may retrieve word variants: tu sach ky tang xa hoi. thi ((van dau) OR (phan dau)) tu va thanh lai ((cua triet) or (cua viet))*.
