2c john » 23 john, 21 john, 25 john
20 john » 10 john, 23 john, 21 john
22 john » 12 john, 23 john
c john » 4 john, 5 john
2 john » 4 john, 5 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 (((20 john) OR (22 john))))) OR (c john))) OR (((2 john) OR (1 john))))) OR (3 john)) %27 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 (c john))) or (((2 john) or (1 john))))) or (3 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((2c john) or (((20 john) OR (22 john))))) or (c john))) or (((2 john) or (1 john))))) or (3 john)) %27 estate%22*.
