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