Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
thanh tung » thanh cong
cap thuoc » cay thuoc, phap thuoc, cap nuoc
cao thuoc » cay thuoc, cua thuoc, nam thuoc
cac phan » cac nhan, cao phan, cap phan
phan dau » phan tu, hang dau

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: doi ((chieu xanh) OR (chieu sang)) - thanh tung ((cap thuoc) OR (cao thuoc)) trong cac phan dau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) OR (chieu sang)) - thanh tung ((cap thuoc) or (cao thuoc)) trong cac phan dau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) OR (chieu sang)) - thanh tung ((cap thuoc) or (cao thuoc)) trong cac phan dau*.
