• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((2c john) OR (c john))) OR (24 john))) OR (((((21 john) OR (22 john))) OR (25 john))))) OR (4 john)) %((27 estate) OR (((1627 estate) OR (1688 estate))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((2c john) or (c john))) or (24 john))) or (((((21 john) or (22 john))) or (25 john))))) or (4 john)) %((27 estate) or (((1627 estate) OR (1688 estate))))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((2c john) or (c john))) or (24 john))) or (((((21 john) or (22 john))) or (25 john))))) or (4 john)) %((27 estate) or (((1627 estate) OR (1688 estate))))%22*.
