Perhaps you should try some spelling variations:
27 estate » 7 estate, 1627 estate
21 john » 11 john, 22 john
25 john » 15 john, 22 john
2c john » 22 john, 20 john, 26 john
23 john » 13 john
24 john » 14 john, 22 john, 20 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 (c john))) OR (24 john))) OR (((((((21 john) OR (1 john))) OR (((2 john) OR (3 john))))) OR (((25 john) OR (5 john))))))) OR (4 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((2c john) or (23 john))) or (c john))) or (24 john))) or (((((((21 john) or (1 john))) or (((2 john) OR (3 john))))) or (((25 john) or (5 john))))))) or (4 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((2c john) or (23 john))) or (c john))) or (24 john))) or (((((((21 john) or (1 john))) or (((2 john) OR (3 john))))) or (((25 john) or (5 john))))))) or (4 john)) %27 estate%22*.
