Perhaps you should try some spelling variations:
1718 estates » 1718 estate, 1712 estate, 1716 estate
24 estimated » 4 estimated, 2 estimated, 24 estimate
3.4 estates » 3.1 estates, 3.4 estimates, 3.4 state
24 estate » 4 estate, 24 estimate, 1824 estates
c john » 1 john, 4 john, 3 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%c john %((_ estate) OR (((((24 estate) OR (24 estimated))) OR (((((18((24 estate) OR (24 estimated))s) OR (3.4 estates))) OR (1718 estates))))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%c john %((_ estate) or (((((24 estate) OR (24 estimated))) or (((((18((24 estate) OR (24 estimated))s) or (3.4 estates))) or (1718 estates))))))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%c john %((_ estate) or (((((24 estate) OR (24 estimated))) or (((((18((24 estate) OR (24 estimated))s) or (3.4 estates))) or (1718 estates))))))%22*.
