Perhaps you should try some spelling variations:
te sach » toc sach
hieu ve » hieu va, hieu van
xuc gia » duc gia, luc gia, tuc gia
van cau » van dau, van hau, van chat
y nang » ky nang, ly nang, v nang
ve cam » ve cham, ve cac, va cam
va cau » va cac, va dau, va cao
x hoi » xa hoi, o hoi, 5 hoi

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang ((x hoi) or (x ho)). hieu ve cam xuc gia thanh ((va cau) OR (van cau)) treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ((x hoi) OR (x ho)). hieu ve cam xuc gia thanh ((va cau) OR (van cau)) treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ((x hoi) or (x ho)). hieu ve cam xuc gia thanh ((va cau) OR (van cau)) treo".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ((x hoi) or (x ho)). hieu ve cam xuc gia thanh ((va cau) OR (van cau)) treo*.
