Perhaps you should try some spelling variations:
te sach » toc sach
cua tre » cua te, cua triet, dua tren
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
cam tuc » cam xuc, cam tu, nam thuc
sach ty » sach y, sach tu, sach thu
cuu tre » cau tren, cau treo
nang ma » tang ma, sang ma, nang cao
nang xa » nang x, lang xa, mang xa
tuc va » thuc va, truc va, tuc xa
va cam » va cham, va cac, va cao

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 ty ((nang xa) OR (nang ma)) hoi. lieu va cam tuc va hanh di ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) or (nang ma)) hoi. lieu va cam tuc va hanh di ((cua tre) OR (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((nang xa) or (nang ma)) hoi. lieu va cam tuc va hanh di ((cua tre) OR (cuu tre))*.
