• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((((((2c john) OR (20 john))) OR (23 john))) OR (c john))) OR (21 john))) OR (((((21 john) OR (22 john))) OR (((25 john) OR (5 john))))))) OR (1 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((((2c john) OR (20 john))) or (23 john))) or (c john))) or (21 john))) or (((((21 john) or (22 john))) or (((25 john) or (5 john))))))) or (1 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((((2c john) OR (20 john))) or (23 john))) or (c john))) or (21 john))) or (((((21 john) or (22 john))) or (((25 john) or (5 john))))))) or (1 john)) %27 estate%22*.
