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