• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((2c john) OR (2((4 john) OR (1 john))))) OR (((((21 john) OR (((((22 john) OR (23 john))) OR (12 john))))) OR (25 john))))) OR (((4 john) OR (1 john)))) %((27 estate) OR (1627 estate))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((2c john) or (2((4 john) or (1 john))))) or (((((21 john) or (((((22 john) OR (23 john))) or (12 john))))) or (25 john))))) or (((4 john) or (1 john)))) %((27 estate) or (1627 estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((2c john) or (2((4 john) or (1 john))))) or (((((21 john) or (((((22 john) OR (23 john))) or (12 john))))) or (25 john))))) or (((4 john) or (1 john)))) %((27 estate) or (1627 estate))%22*.
