• If you are trying to use Boolean operators, they must be ALL CAPS: %22polycarp %((((((2f saint) OR (21 saint))) OR (((25 saint) OR (((15 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 (21 saint))) or (((25 saint) or (((15 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 (21 saint))) or (((25 saint) or (((15 saint) or (14 saint))))))) or (a saint))%r.c bishop of smyrna%22*.
