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