• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((c john) or (((((22 john) or (((((13 john) or (10 john))) or (3 john))))) or (((12 john) OR (16 john)))))) %((((2f estate) or (27 estate))) or (_ estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((c john) or (((((22 john) or (((((13 john) or (10 john))) or (3 john))))) or (((12 john) OR (16 john)))))) %((((2f estate) or (27 estate))) or (_ estate))%22*.
