2c john » 22 john, 25 john, 20 john
13 john » 1 john, 10 john, 11 john
21 john » 1 john, 11 john, 22 john
c john » 1 john, 5 john
4 john » 1 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 (((23 john) OR (13 john))))) OR (((21 john) OR (4 john))))) OR (3 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((2c john) OR (c john))) or (((23 john) or (13 john))))) or (((21 john) or (4 john))))) or (3 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((2c john) OR (c john))) or (((23 john) or (13 john))))) or (((21 john) or (4 john))))) or (3 john)) %27 estate%22*.
