Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nang xa » nang x, lang xa, mang xa
nang ma » tang ma, sang ma, nang cao
hieu ve » hieu va, hieu van
vi cua » vai cua, di cua
luc va » duc va, tuc va, loc va
xuc va » duc va, tuc va, xac va
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ve cac » va cac, vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky ((nang xa) OR (nang ma)) hoi. hieu ve cac ((xuc va) or (luc va)) hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((nang xa) OR (nang ma)) hoi. hieu ve cac ((xuc va) OR (luc va)) hanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((nang xa) OR (nang ma)) hoi. hieu ve cac ((xuc va) or (luc va)) hanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: su sac ky ((nang xa) OR (nang ma)) hoi. hieu ve cac ((xuc va) or (luc va)) hanh vi cua triet*.
