• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((2c john) OR (20 john))) OR (24 john))) OR (((((21 john) OR (((22 john) OR (((12 john) OR (2 john))))))) OR (15 john))))) OR (4 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((2c john) or (20 john))) or (24 john))) or (((((21 john) or (((22 john) or (((12 john) OR (2 john))))))) or (15 john))))) or (4 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((2c john) or (20 john))) or (24 john))) or (((((21 john) or (((22 john) or (((12 john) OR (2 john))))))) or (15 john))))) or (4 john)) %27 estate%22*.
