20 john » 10 john, 24 john, 2008 john
22 john » 2 john, 12 john
23 john » 3 john
11 john » 12 john
13 john » 3 john, 10 john, 12 john
c john » 4 john, 3 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%((((((((((25 john) OR (((((20 john) OR (21 john))) OR (22 john))))) OR (23 john))) OR (c john))) OR (((11 john) OR (1 john))))) OR (13 john)) %_ estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((25 john) or (((((20 john) OR (21 john))) or (22 john))))) or (23 john))) or (c john))) or (((11 john) or (1 john))))) or (13 john)) %_ estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((25 john) or (((((20 john) OR (21 john))) or (22 john))))) or (23 john))) or (c john))) or (((11 john) or (1 john))))) or (13 john)) %_ estate%22*.
