Perhaps you should try some spelling variations:
te sach » toc sach
duc ban » duc tan, duc van, dua ban
xuc ban » cuc ban, quoc ban, xuat ban
ve cham » va cham, ve chat, vu cham
sach ky » sac ky, sach y, sach ty
hieu ve » hieu va, hieu van
mai hoi » mai khoi, dai hoi, lai hoi
ky sang » ky nang, ky dang, ky tang
ma hoi » xa hoi, ma hoa, me hoi
vi cua » vai cua, di cua
cua te » cua tu

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: te sach ky sang ((ma hoi) OR (mai hoi)). hieu ve cham ((xuc ban) OR (duc ban)) hanh vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky sang ((ma hoi) or (mai hoi)). hieu ve cham ((xuc ban) OR (duc ban)) hanh vi cua te~".
• Adding a wildcard symbol may retrieve word variants: te sach ky sang ((ma hoi) or (mai hoi)). hieu ve cham ((xuc ban) OR (duc ban)) hanh vi cua te*.
