Perhaps you should try some spelling variations:
vu sach » vu bach, su sach, vu khach
bo sach » co sach, hoc sach
ky danh » ky anh, ky dang
danh xa » danh ca, dinh xa, canh xa
hieu va » lieu va, hieu qua
danh vi » hanh vi, dinh vi, danh di
xuc va » tuc va, luc va, xac va
vi cua » vai cua, di 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 (bo sach)) ky danh xa hoi. hieu va cac ((xuc va) OR (duc va)) danh vi cua vat~.
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (bo sach)) ky danh xa hoi. hieu va cac ((xuc va) or (duc va)) danh vi cua vat*.
