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