Perhaps you should try some spelling variations:
_ estate » _ estates, _ estimate
2c john » c john, 25 john, 20 john
21 john » 1 john, 11 john, 25 john
22 john » 2 john, 12 john
23 john » 3 john, 13 john

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 (22 john))))) OR (23 john)) %((ai estate) OR (_ estate))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((2c john) or (((21 john) OR (22 john))))) or (23 john)) %((ai estate) or (_ estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((2c john) or (((21 john) OR (22 john))))) or (23 john)) %((ai estate) or (_ estate))%22*.
