• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((((2c john) OR (c john))) OR (15 john))) OR (21 john))) OR (1 john))) OR (22 john)) %((2f estate) OR (((24 estate) OR (24 estimated))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((2c john) OR (c john))) or (15 john))) or (21 john))) or (1 john))) or (22 john)) %((2f estate) or (((24 estate) or (24 estimated))))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((2c john) OR (c john))) or (15 john))) or (21 john))) or (1 john))) or (22 john)) %((2f estate) or (((24 estate) or (24 estimated))))%22*.
