Perhaps you should try some spelling variations:
27 estate » 7 estate, 1627 estate
20 john » 10 john, 21 john, 25 john
23 john » 13 john
12 john » 2 john, 11 john
16 john » 10 john, 6 john
22 john » 2 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%((((((20 john) OR (((23 john) OR (((12 john) OR (16 john))))))) OR (((((22 john) OR (1 john))) OR (((2((5 john) OR (4 john))) OR (((5 john) OR (4 john))))))))) OR (3 john)) %27 estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((20 john) or (((23 john) or (((12 john) or (16 john))))))) or (((((22 john) or (1 john))) or (((2((5 john) OR (4 john))) or (((5 john) OR (4 john))))))))) or (3 john)) %27 estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((20 john) or (((23 john) or (((12 john) or (16 john))))))) or (((((22 john) or (1 john))) or (((2((5 john) OR (4 john))) or (((5 john) OR (4 john))))))))) or (3 john)) %27 estate%22*.
