Perhaps you should try some spelling variations:
20 john » 10 john, 23 john, 24 john
22 john » 2 john, 12 john, 23 john
25 john » 15 john, 23 john
21 john » 11 john, 23 john
13 john » 3 john, 10 john, 11 john
c john » 4 john, 3 john
5 john » 4 john, 3 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 (5 john))) OR (((20 john) OR (22 john))))) OR (25 john))) OR (((c john) OR (5 john))))) OR (((21 john) OR (1 john))))) OR (13 john)) %_ estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((2((c john) OR (5 john))) or (((20 john) or (22 john))))) or (25 john))) or (((c john) OR (5 john))))) or (((21 john) or (1 john))))) or (13 john)) %_ estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((2((c john) OR (5 john))) or (((20 john) or (22 john))))) or (25 john))) or (((c john) OR (5 john))))) or (((21 john) or (1 john))))) or (13 john)) %_ estate%22*.
