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