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