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