25 john » 5 john, 15 john
21 john » 1 john, 11 john
23 john » 13 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 (3 john))) OR (23 john))) OR (((c john) OR (3 john))))) OR (24 john))) OR (((((21 john) OR (22 john))) OR (25 john))))) OR (4 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((2((c john) OR (3 john))) or (23 john))) or (((c john) OR (3 john))))) or (24 john))) or (((((21 john) or (22 john))) or (25 john))))) or (4 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((2((c john) OR (3 john))) or (23 john))) or (((c john) OR (3 john))))) or (24 john))) or (((((21 john) or (22 john))) or (25 john))))) or (4 john)) %27 estate%22*.
