• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((21 john) OR (1 john))) OR (((24 john) OR (((14 john) OR (4 john)))))) %((((2f estate) OR (_ estate))) OR (27 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 (((14 john) or (4 john)))))) %((((2f estate) OR (_ estate))) or (27 estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((21 john) or (1 john))) or (((24 john) or (((14 john) or (4 john)))))) %((((2f estate) OR (_ estate))) or (27 estate))%22*.
