Perhaps you should try some spelling variations:
27 estate » 7 estate, 1627 estate
2f estate » 24 estate, _ estate, ai estate
21 john » 2 john, 11 john, 22 john
23 john » 3 john, 2 john
13 john » 3 john, 10 john, 11 john
c john » 3 john, 4 john, 2 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%((((((2((c john) OR (1 john))) OR (((c john) OR (1 john))))) OR (21 john))) OR (((23 john) OR (13 john)))) %((2f estate) OR (27 estate))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((2((c john) or (1 john))) or (((c john) or (1 john))))) or (21 john))) or (((23 john) or (13 john)))) %((2f estate) OR (27 estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((2((c john) or (1 john))) or (((c john) or (1 john))))) or (21 john))) or (((23 john) or (13 john)))) %((2f estate) OR (27 estate))%22*.
