Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
hien xanh » hien nhanh, chieu xanh, hien khanh
hien hanh » dieu hanh
nang dang » nang sang, nang dong, nang hang
trong san » trong cac, cong san, dong san
san than » sang than, san thanh, ban than
than cau » toan cau, phan cau, than cap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((((hien xanh) OR (hien hanh))) or (chieu sang)) - nang dang su dung trong san than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((hien xanh) OR (hien hanh))) OR (chieu sang)) - nang dang su dung trong san than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((hien xanh) OR (hien hanh))) or (chieu sang)) - nang dang su dung trong san than cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((((hien xanh) OR (hien hanh))) or (chieu sang)) - nang dang su dung trong san than cau*.
