2c john » 23 john, 22 john, 21 john
c john » 1 john, 3 john, 5 john
2 john » 1 john, 3 john, 5 john

• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((2c john) or (c john))) or (((2((2 john) OR (4 john))) or (((1((2 john) OR (4 john))) or (((2 john) OR (4 john)))))))) %2f estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((2c john) or (c john))) or (((2((2 john) OR (4 john))) or (((1((2 john) OR (4 john))) or (((2 john) OR (4 john)))))))) %2f estate%22*.
