• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu xanh) OR (thien anh)) - canh doanh thanh dung ((cong thanh) OR (cong tan)) phan tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu xanh) or (thien anh)) - canh doanh thanh dung ((cong thanh) OR (cong tan)) phan tu".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu xanh) or (thien anh)) - canh doanh thanh dung ((cong thanh) OR (cong tan)) phan tu*.
