• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((((23 john) or (3 john))) or (13 john))) or (20 john))) or (2((4 john) OR (1 john))))) or (((((21 john) or (((22 john) or (12 john))))) or (25 john))))) or (((4 john) OR (1 john)))) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((((23 john) or (3 john))) or (13 john))) or (20 john))) or (2((4 john) OR (1 john))))) or (((((21 john) or (((22 john) or (12 john))))) or (25 john))))) or (((4 john) OR (1 john)))) %27 estate%22*.
