Perhaps you should try some spelling variations:
2f estate » 24 estate, 27 estate, ai estate
_ estate » _ estates, _ estimate
2c john » c john, 22 john, 21 john
23 john » 13 john
2 john » 1 john, 5 john
4 john » 1 john
3 john » 1 john

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((2c john) OR (((((((2((2 john) OR (4 john))) OR (((2 john) OR (4 john))))) OR (((23 john) OR (3 john))))) OR (1((2 john) OR (4 john)))))) %((2f estate) OR (_ estate))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((2c john) or (((((((2((2 john) OR (4 john))) or (((2 john) OR (4 john))))) or (((23 john) or (3 john))))) or (1((2 john) OR (4 john)))))) %((2f estate) or (_ estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((2c john) or (((((((2((2 john) OR (4 john))) or (((2 john) OR (4 john))))) or (((23 john) or (3 john))))) or (1((2 john) OR (4 john)))))) %((2f estate) or (_ estate))%22*.
