• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((2c john) OR (23 john))) or (15 john))) or (21 john))) or (1 john))) or (22 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((2c john) OR (23 john))) or (15 john))) or (21 john))) or (1 john))) or (22 john)) %27 estate%22*.
