Perhaps you should try some spelling variations:
27 estate » 7 estate, 1627 estate
2c john » c john, 23 john, 22 john
21 john » 23 john, 22 john, 25 john
11 john » 12 john
3 john » 4 john
5 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 (2((3 john) OR (1 john))))) OR (((((21 john) OR (11 john))) OR (5 john))))) OR (((3 john) OR (1 john)))) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((2c john) or (2((3 john) or (1 john))))) or (((((21 john) OR (11 john))) or (5 john))))) or (((3 john) or (1 john)))) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((2c john) or (2((3 john) or (1 john))))) or (((((21 john) OR (11 john))) or (5 john))))) or (((3 john) or (1 john)))) %27 estate%22*.
