Perhaps you should try some spelling variations:
danh lai » danh sai, gianh lai, dinh lam
va trien » va truyen, va thiet, va tuyen
hieu van » hieu va, thien van, lieu va
va triet » va thiet, ve triet, cua triet
cac thuc » cach thuc, cac thu, can thuc
sach thi » sach thu, sach tai, sach thieu
tu sach » thu sach, su sach, te sach
thuc va » thuc vat, thuc dan, thuc day
va danh » va dinh, va dan, va hanh
van cac » van hac, van cau, van bac
thi lan » thi hanh, thi nang, thi lien
lan xa » lang xa, dan xa, lan ha

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