• If you are trying to use Boolean operators, they must be ALL CAPS: %22polycarp %((((15 saint) OR (_ saint))) OR (((((((2_ saint) OR (25 saint))) OR (21 saint))) OR (2015 joint))))%2c bishop of smyrna%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22polycarp %((((15 saint) or (_ saint))) or (((((((2_ saint) OR (25 saint))) or (21 saint))) or (2015 joint))))%2c bishop of smyrna%22".
• Adding a wildcard symbol may retrieve word variants: %22polycarp %((((15 saint) or (_ saint))) or (((((((2_ saint) OR (25 saint))) or (21 saint))) or (2015 joint))))%2c bishop of smyrna%22*.
