Perhaps you should try some spelling variations:
27 estate » 7 estate, 1627 estate
2c john » 23 john, 25 john, 20 john
21 john » 11 john, 23 john, 25 john
22 john » 2 john, 23 john
12 john » 2 john, 11 john
c john » 3 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%((((((((2c john) OR (c john))) OR (21 john))) OR (((21 john) OR (((22 john) OR (12 john))))))) OR (1 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((2c john) OR (c john))) or (21 john))) or (((21 john) or (((22 john) or (12 john))))))) or (1 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((2c john) OR (c john))) or (21 john))) or (((21 john) or (((22 john) or (12 john))))))) or (1 john)) %27 estate%22*.
