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