Perhaps you should try some spelling variations:
27 estate » 7 estate, 1627 estate
2c john » c john, 23 john, 25 john
22 john » 2 john, 23 john
24 john » 14 john, 23 john, 25 john
21 john » 11 john, 23 john, 25 john
12 john » 2 john, 16 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 (22 john))) OR (24 john))) OR (((((21 john) OR (1 john))) OR (12 john))))) OR (4 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((2c john) OR (22 john))) or (24 john))) or (((((21 john) or (1 john))) or (12 john))))) or (4 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((2c john) OR (22 john))) or (24 john))) or (((((21 john) or (1 john))) or (12 john))))) or (4 john)) %27 estate%22*.
