Perhaps you should try some spelling variations:
tieu xanh » tieu danh, chieu xanh, dieu hanh
hanh dong » anh dong, ha dong
cua khong » hua khong, cua phuong, cua thuong
anh dang » anh dong, anh dung, anh bang
cong anh » cong danh, dong anh, cong thanh
hong anh » hoang anh, hong hanh, dong anh
tuan cau » toan cau, quan cau, tuan cu

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: theo tieu xanh - ((hanh dong) OR (anh dang)) cua khong ((cong anh) OR (hong anh)) tuan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu xanh - ((hanh dong) or (anh dang)) cua khong ((cong anh) OR (hong anh)) tuan cau~".
• Adding a wildcard symbol may retrieve word variants: theo tieu xanh - ((hanh dong) or (anh dang)) cua khong ((cong anh) OR (hong anh)) tuan cau*.
