Perhaps you should try some spelling variations:
27 estate » 7 estate, 1627 estate
2c john » c john, 22 john, 21 john
23 john » 3 john, 13 john
11 john » 12 john
25 john » 5 john, 15 john, 22 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 (23 john))) OR (2((4 john) OR (1 john))))) OR (((11 john) OR (25 john))))) OR (((4 john) OR (1 john)))) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((2c john) OR (23 john))) or (2((4 john) or (1 john))))) or (((11 john) or (25 john))))) or (((4 john) or (1 john)))) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((2c john) OR (23 john))) or (2((4 john) or (1 john))))) or (((11 john) or (25 john))))) or (((4 john) or (1 john)))) %27 estate%22*.
