Perhaps you should try some spelling variations:
cau triet » cau trieu, su triet, cua triet
cau treo » cau theo, cau tren, cau trieu
te sach » toc sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve chat » va chat, van chat
xuc va » duc va, tuc va, luc va

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 ky nang xa hoi. hieu ve chat ((xuc va) or (thuc vat)) than kinh ((cau treo) OR (cau triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ve chat ((xuc va) OR (thuc vat)) than kinh ((cau treo) OR (cau triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu ve chat ((xuc va) or (thuc vat)) than kinh ((cau treo) OR (cau triet))".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang xa hoi. hieu ve chat ((xuc va) or (thuc vat)) than kinh ((cau treo) OR (cau triet))*.
