Perhaps you should try some spelling variations:
te sach » toc sach
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
sach ty » sach y, sach tu, sach thu
hieu va » hieu qua
nang xa » lang xa, nang ma, mang xa
cuu tre » cua tre, cau tren, cau treo
nam tu » nam thu, nam thuc
di cuu » di cau, di cua, dinh cuu

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 ty ((nang xa) OR (nang x)) hoi. ((hieu va) or (lieu va)) nam tu va hanh di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang xa) OR (nang x)) hoi. ((hieu va) OR (lieu va)) nam tu va hanh di cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) OR (nang x)) hoi. ((hieu va) or (lieu va)) nam tu va hanh di cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((nang xa) OR (nang x)) hoi. ((hieu va) or (lieu va)) nam tu va hanh di cuu tre*.
