• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((((((((2c john) OR (25 john))) OR (((15 john) OR (10 john))))) OR (21 john))) OR (1 john))) OR (22 john)) %2f estate%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22orlebar%((((((((((2c john) or (25 john))) or (((15 john) OR (10 john))))) or (21 john))) or (1 john))) or (22 john)) %2f estate%22".
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((((((((2c john) or (25 john))) or (((15 john) OR (10 john))))) or (21 john))) or (1 john))) or (22 john)) %2f estate%22*.
