• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((2c john) OR (c john))) OR (((((23 john) OR (((2 john) OR (4 john))))) OR (((1((2 john) OR (4 john))) OR (16 john)))))) %2f estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((2c john) or (c john))) or (((((23 john) or (((2 john) OR (4 john))))) or (((1((2 john) OR (4 john))) or (16 john)))))) %2f estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((2c john) or (c john))) or (((((23 john) or (((2 john) OR (4 john))))) or (((1((2 john) OR (4 john))) or (16 john)))))) %2f estate%22*.
