Perhaps you should try some spelling variations:
cua viet » ca viet, hoa viet, cua vat
hieu van » thien van, lieu va, hieu ve
tinh ve » trinh ve, tinh ven, dinh ve
va tinh » may tinh
lam xuc » cam xuc, lam duoc
hieu va » lieu va, hieu qua
vu sach » vu bach, su sach, vu khach
dinh xa » dinh ba, dinh va, dinh xu
ky dinh » ky sinh, ky danh, ky kinh
so sanh » do sanh
xuc va » duc va, tuc va, luc va
ve cua » le cua, de cua, te cua

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (so sanh)) ky dinh xa hoi. ((hieu van) OR (hieu va)) lam xuc va tinh ve cua viet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (so sanh)) ky dinh xa hoi. ((hieu van) OR (hieu va)) lam xuc va tinh ve cua viet~".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (so sanh)) ky dinh xa hoi. ((hieu van) OR (hieu va)) lam xuc va tinh ve cua viet*.
