Perhaps you should try some spelling variations:
cau theo » cau thi, cau tao
thanh vi » hanh vi, thanh va, thanh ve
hanh va » hang va, hanh vi
xuc gia » duc gia, luc gia, tuc gia
te sach » toc sach
xay hoi » xa hoi, tay hoi, cay phoi
hieu ve » hieu va, hieu van
y dang » ky dang, _ dang, b dang
ve cam » ve cham, ve cac, va cam
2 dang » 2 danh, _ dang, b dang

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 dang) OR (2 dang)) xay hoi. hieu ve cam xuc gia ((thanh vi) or (hanh va)) cau theo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y dang) OR (2 dang)) xay hoi. hieu ve cam xuc gia ((thanh vi) OR (hanh va)) cau theo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y dang) OR (2 dang)) xay hoi. hieu ve cam xuc gia ((thanh vi) or (hanh va)) cau theo".
• Adding a wildcard symbol may retrieve word variants: te sach ((y dang) OR (2 dang)) xay hoi. hieu ve cam xuc gia ((thanh vi) or (hanh va)) cau theo*.
