Perhaps you should try some spelling variations:
27 estate » 7 estate, 1627 estate
2f estate » 24 estate, _ estate, ai estate
2c john » 2 john, 23 john, 22 john
21 john » 1 john, 2 john, 11 john
16 john » 1 john, 6 john
c john » 1 john, 4 john, 2 john
3 john » 1 john, 4 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 (c john))) OR (21 john))) OR (((((16 john) OR (10 john))) OR (3 john)))) %((2f estate) OR (27 estate))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((2c john) or (c john))) or (21 john))) or (((((16 john) or (10 john))) or (3 john)))) %((2f estate) OR (27 estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((2c john) or (c john))) or (21 john))) or (((((16 john) or (10 john))) or (3 john)))) %((2f estate) OR (27 estate))%22*.
