• If you are trying to use Boolean operators, they must be ALL CAPS: doi hieu lang - ((manh tuong) OR (manh tung)) cua nhung cong quang ((hoan cap) OR (hoang cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi hieu lang - ((manh tuong) or (manh tung)) cua nhung cong quang ((hoan cap) OR (hoang cao))*".
