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