• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((2c john) OR (23 john))) OR (21 john))) OR (1 john))) OR (((22 john) OR (((12 john) OR (2 john)))))) %2f estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((2c john) or (23 john))) or (21 john))) or (1 john))) or (((22 john) or (((12 john) OR (2 john)))))) %2f estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((2c john) or (23 john))) or (21 john))) or (1 john))) or (((22 john) or (((12 john) OR (2 john)))))) %2f estate%22*.
