Perhaps you should try some spelling variations:
2c john » 21 john, 25 john, 24 john
20 john » 10 john, 21 john, 25 john
22 john » 2 john
23 john » 3 john
12 john » 2 john
13 john » 3 john, 14 john, 15 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 (((20 john) OR (22 john))))) OR (23 john))) OR (c john))) OR (((((11 john) OR (12 john))) OR (1 john))))) OR (13 john)) %_ estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((2c john) or (((20 john) or (22 john))))) or (23 john))) or (c john))) or (((((11 john) OR (12 john))) or (1 john))))) or (13 john)) %_ estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((2c john) or (((20 john) or (22 john))))) or (23 john))) or (c john))) or (((((11 john) OR (12 john))) or (1 john))))) or (13 john)) %_ estate%22*.
