Perhaps you should try some spelling variations:
2f estate » 24 estate, _ estate, ai estate
27 estate » 7 estate, 1627 estate
2c john » 23 john, 22 john, 25 john
21 john » 1 john, 11 john, 23 john
12 john » 2 john, 11 john
c john » 1 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 (c john))) OR (21 john))) OR (12 john)) %((2f estate) OR (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 (12 john)) %((2f estate) or (27 estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((2c john) OR (c john))) or (21 john))) or (12 john)) %((2f estate) or (27 estate))%22*.
