• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((21 john) OR (1 john))) OR (((24 john) OR (((((16 john) OR (12 john))) OR (4 john)))))) %((2f estate) OR (_ estate))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((21 john) or (1 john))) or (((24 john) or (((((16 john) or (12 john))) or (4 john)))))) %((2f estate) OR (_ estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((21 john) or (1 john))) or (((24 john) or (((((16 john) or (12 john))) or (4 john)))))) %((2f estate) OR (_ estate))%22*.
