Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
thuc ban » thuoc ban, thuc dan, thu ban
tuc ban » truc ban, tu ban, tuc dan
so sanh » do sanh
sanh ky » hanh ky, sang ky, nganh ky
lang xa » lang ha, dang xay, lang van
nang xa » nang x, nang ma, mang xa
van cam » van nam, van lam, van cau
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: so sanh ky ((nang xa) OR (lang xa)) hoi. hieu van cam ((tuc ban) or (thuc ban)) hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ky ((nang xa) OR (lang xa)) hoi. hieu van cam ((tuc ban) OR (thuc ban)) hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ky ((nang xa) OR (lang xa)) hoi. hieu van cam ((tuc ban) or (thuc ban)) hanh vi cua triet*".
