Perhaps you should try some spelling variations:
27 estate » 1627 estate
7 estate » _ estate, 3 estate, 4 estate
23 john » 13 john
20 john » 10 john, 22 john, 25 john
21 john » 11 john, 22 john, 25 john
3 john » 4 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%((((((((23 john) OR (20 john))) OR (3 john))) OR (((21 john) OR (1 john))))) OR (23 john)) %((27 estate) OR (7 estate))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((23 john) or (20 john))) or (3 john))) or (((21 john) or (1 john))))) or (23 john)) %((27 estate) OR (7 estate))%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((23 john) or (20 john))) or (3 john))) or (((21 john) or (1 john))))) or (23 john)) %((27 estate) OR (7 estate))%22*.
