Perhaps you should try some spelling variations:
27 estate » 7 estate, 1627 estate
2c john » 22 john, 25 john, 24 john
20 john » 10 john, 22 john, 25 john
21 john » 11 john, 22 john, 25 john
23 john » 13 john
c john » 4 john, 5 john
3 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 (20 john))) OR (c john))) OR (((((21 john) OR (23 john))) OR (1 john))))) OR (3 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((2c john) or (20 john))) or (c john))) or (((((21 john) OR (23 john))) or (1 john))))) or (3 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((2c john) or (20 john))) or (c john))) or (((((21 john) OR (23 john))) or (1 john))))) or (3 john)) %27 estate%22*.
