_ estate » _ estates, _ estimate
2c john » 25 john, 24 john, 26 john
22 john » 2 john, 12 john

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