• If you are trying to use Boolean operators, they must be ALL CAPS: %22polycarp %((((((2f saint) OR (((2 saint) OR (1 saint))))) OR (((2((5 saint) OR (5 saints))) OR (((5 saint) OR (5 saints))))))) OR (21 saint))%2c bishop of smyrna%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22polycarp %((((((2f saint) or (((2 saint) or (1 saint))))) or (((2((5 saint) OR (5 saints))) or (((5 saint) OR (5 saints))))))) or (21 saint))%2c bishop of smyrna%22".
• Adding a wildcard symbol may retrieve word variants: %22polycarp %((((((2f saint) or (((2 saint) or (1 saint))))) or (((2((5 saint) OR (5 saints))) or (((5 saint) OR (5 saints))))))) or (21 saint))%2c bishop of smyrna%22*.
