Perhaps you should try some spelling variations:
27 estate » 7 estate, 1627 estate
ai estate » _ estate
23 john » 3 john, 13 john
22 john » 2 john, 12 john
c john » 1 john, 3 john
5 john » 1 john, 3 john
4 john » 1 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%((((((2((((c john) OR (5 john))) OR (4 john))) OR (((((c john) OR (5 john))) OR (4 john))))) OR (22 john))) OR (23 john)) %((ai estate) OR (27 estate))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((2((((c john) OR (5 john))) or (4 john))) or (((((c john) OR (5 john))) or (4 john))))) or (22 john))) or (23 john)) %((ai estate) or (27 estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((2((((c john) OR (5 john))) or (4 john))) or (((((c john) OR (5 john))) or (4 john))))) or (22 john))) or (23 john)) %((ai estate) or (27 estate))%22*.
