• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((((24 john) OR (23 john))) OR (4 john))) OR (((21 john) OR (25 john))))) OR (((((((21 john) OR (25 john))) OR (((22 john) OR (2 john))))) OR (((15 john) OR (5 john))))))) OR (1 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((24 john) or (23 john))) or (4 john))) or (((21 john) OR (25 john))))) or (((((((21 john) OR (25 john))) or (((22 john) or (2 john))))) or (((15 john) or (5 john))))))) or (1 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((24 john) or (23 john))) or (4 john))) or (((21 john) OR (25 john))))) or (((((((21 john) OR (25 john))) or (((22 john) or (2 john))))) or (((15 john) or (5 john))))))) or (1 john)) %27 estate%22*.
