Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
danh bat » doanh bat, anh bai, dinh ba
danh sai » dung sai, danh dau, hanh san
hieu van » hieu va, thien van, lieu va
thu sach » tu sach, thuat sach, thuoc sach
sach ty » sach y, sach tu, sach thu
truc va » thuc va, thuc vat, trung va
nang xa » lang xa, nang ma, mang xa
van cau » van dau, van hau, van chat

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty ((nang xa) OR (nang x)) hoi. hieu van cau truc va ((danh sai) or (danh bat)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty ((nang xa) OR (nang x)) hoi. hieu van cau truc va ((danh sai) OR (danh bat)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty ((nang xa) OR (nang x)) hoi. hieu van cau truc va ((danh sai) or (danh bat)) cua triet*".
