Perhaps you should try some spelling variations:
te sach » toc sach
hanh de » hanh ve, hanh kem
va hanh » van hanh, va thanh, va danh
cam duc » cao duc, pham duc, nam duoc
hieu va » lieu va, hieu qua
cau tre » cau tren, cau treo, cau tra
nang xa » nang x, lang xa, mang xa
nang ma » tang ma, sang ma, nang cao
de cau » ke cau, le cau, ve cau

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 xa) OR (nang ma)) hoi. hieu va ((cam duc) or (cam xuc)) va hanh de cau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang xa) OR (nang ma)) hoi. hieu va ((cam duc) OR (cam xuc)) va hanh de cau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang xa) OR (nang ma)) hoi. hieu va ((cam duc) or (cam xuc)) va hanh de cau tre".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang xa) OR (nang ma)) hoi. hieu va ((cam duc) or (cam xuc)) va hanh de cau tre*.
