Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
dan danh » van danh, han danh, ban danh
thuc dan » thuc hanh, hoc dan, thuc vat
danh vi » hanh vi, dinh vi, danh di
ban dan » ban hang, ban hanh, ban quan
bo sach » co sach, hoc sach
nang xa » nang x, lang xa, mang xa
nang ma » tang ma, sang ma, nang cao
van dan » van ban, van dao, van dau
vi cua » vai cua, di cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: bo sach y ((nang xa) or (nang ma)) hoi. hieu ((van dan) OR (ban dan)) thuc dan danh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: bo sach y ((nang xa) OR (nang ma)) hoi. hieu ((van dan) OR (ban dan)) thuc dan danh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "bo sach y ((nang xa) or (nang ma)) hoi. hieu ((van dan) OR (ban dan)) thuc dan danh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: bo sach y ((nang xa) or (nang ma)) hoi. hieu ((van dan) OR (ban dan)) thuc dan danh vi cua triet*.
