• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((c john) OR (((((22 john) OR (((((13 john) OR (10 john))) OR (3 john))))) OR (((12 john) OR (2 john)))))) %((((2f estate) OR (1627 estate))) OR (_ estate))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((c john) or (((((22 john) or (((((13 john) or (10 john))) or (3 john))))) or (((12 john) OR (2 john)))))) %((((2f estate) or (1627 estate))) or (_ estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((c john) or (((((22 john) or (((((13 john) or (10 john))) or (3 john))))) or (((12 john) OR (2 john)))))) %((((2f estate) or (1627 estate))) or (_ estate))%22*.
