• If you are trying to use Boolean operators, they must be ALL CAPS: %22polycarp %((((2f saint) OR (((25 saint) OR (((((15 saint) OR (1 saint))) OR (14 saint))))))) OR (a saint))%r.c bishop of smyrna%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22polycarp %((((2f saint) or (((25 saint) or (((((15 saint) OR (1 saint))) or (14 saint))))))) or (a saint))%r.c bishop of smyrna%22".
• Adding a wildcard symbol may retrieve word variants: %22polycarp %((((2f saint) or (((25 saint) or (((((15 saint) OR (1 saint))) or (14 saint))))))) or (a saint))%r.c bishop of smyrna%22*.
