Perhaps you should try some spelling variations:
24 estimate » 24 estimated, 24 estimates, 2 estimate
27 estate » 7 estate, 1627 estate
2c john » c john, 22 john, 21 john
23 john » 13 john
2 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 (2((2 john) OR (3 john))))) OR (((23 john) OR (((2 john) OR (3 john)))))) %((24 estimate) OR (27 estate))%22*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((2c john) or (2((2 john) OR (3 john))))) or (((23 john) or (((2 john) OR (3 john)))))) %((24 estimate) or (27 estate))%22*".
