Perhaps you should try some spelling variations:
1718 estate » 1718 estates, 1778 estate, 1712 estate
24 estate » 24 estimate, 1824 estates, 24 estimated
4 estate » 3 estate, 4 estimate, ai estate
c john » 3 john, 4 john, 5 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) OR (1 john)) %((_ estate) OR (((((24 estate) OR (4 estate))) OR (1718 estate))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((c john) OR (1 john)) %((_ estate) or (((((24 estate) or (4 estate))) or (1718 estate))))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((c john) OR (1 john)) %((_ estate) or (((((24 estate) or (4 estate))) or (1718 estate))))%22*.
