• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((((2c john) OR (23 john))) OR (c john))) OR (24 john))) OR (((((21 john) OR (((22 john) OR (12 john))))) OR (((25 john) OR (5 john))))))) OR (4 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((2c john) or (23 john))) or (c john))) or (24 john))) or (((((21 john) or (((22 john) OR (12 john))))) or (((25 john) or (5 john))))))) or (4 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((2c john) or (23 john))) or (c john))) or (24 john))) or (((((21 john) or (((22 john) OR (12 john))))) or (((25 john) or (5 john))))))) or (4 john)) %27 estate%22*.
