• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - hanh han cua hang ((((cong dan) OR (cong tan))) OR (cong thanh)) toan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - hanh han cua hang ((((cong dan) OR (cong tan))) or (cong thanh)) toan ban*".
