Perhaps you should try some spelling variations:
27 estate » 7 estate, 1627 estate
21 john » 11 john
23 john » 3 john
13 john » 3 john, 10 john, 11 john
94 john » 14 john, 24 john, 1994 john
22 john » 2 john, 12 john
25 john » 5 john, 15 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%((((((((((21 john) OR (((23 john) OR (13 john))))) OR (1 john))) OR (94 john))) OR (((((21 john) OR (22 john))) OR (25 john))))) OR (4 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((21 john) or (((23 john) OR (13 john))))) or (1 john))) or (94 john))) or (((((21 john) or (22 john))) or (25 john))))) or (4 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((21 john) or (((23 john) OR (13 john))))) or (1 john))) or (94 john))) or (((((21 john) or (22 john))) or (25 john))))) or (4 john)) %27 estate%22*.
