Perhaps you should try some spelling variations:
2f estate » 24 estate, 27 estate, ai estate
_ estate » _ estimate
2c john » c john, 22 john, 25 john
21 john » 11 john, 22 john, 25 john
23 john » 3 john, 13 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 (21 john))) OR (1 john))) OR (23 john)) %((((2f estate) OR (_ estate))) OR (_ estates))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((2c john) or (21 john))) or (1 john))) or (23 john)) %((((2f estate) OR (_ estate))) or (_ estates))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((2c john) or (21 john))) or (1 john))) or (23 john)) %((((2f estate) OR (_ estate))) or (_ estates))%22*.
