• The words AND, OR and NOT may confuse the search; try adding quotes: "((studying charisma) or (studying china's)) - ((band 0.1) or (((band 13.1) OR (band 3.1))))".
• Adding a wildcard symbol may retrieve word variants: ((studying charisma) or (studying china's)) - ((band 0.1) or (((band 13.1) OR (band 3.1))))*.
