Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thuc van » thuc vat, thuc dan, thuc va
su sach » vu sach
so sach » so sanh, bo sach, co sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
tuc van » truc van, tuc va, duc van
ve cam » ve cham, ve cac, va cam
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: ((su sach) or (so sach)) ky nang xa hoi. hieu ve cam ((tuc van) OR (thuc van)) hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ky nang xa hoi. hieu ve cam ((tuc van) OR (thuc van)) hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) ky nang xa hoi. hieu ve cam ((tuc van) OR (thuc van)) hanh vi cua triet*".
