Perhaps you should try some spelling variations:
1627 estate » 1636 estate, 1650 estate, 1688 estate
24 estimate » 24 estimated, 24 estimates, 4 estimate
2 estimate » 2 estimates, _ estimate, 2 estimation
24 estate » 4 estate, 1824 estates, 24 estimated
c john » 1 john, 4 john, 3 john

Try widening your search to All Fields.

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 %((1627 estate) OR (((((24 estate) OR (24 estimate))) OR (2 estimate))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%c john %((1627 estate) or (((((24 estate) OR (24 estimate))) or (2 estimate))))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%c john %((1627 estate) or (((((24 estate) OR (24 estimate))) or (2 estimate))))%22*.
