d.d bishop » ld bishop
r.c bishop » f.r.s bishop
2c bishop » 128 bishop, m.c bishop, a bishop
21 bishop » 11 bishop, 128 bishop, a bishop
25 saint » 5 saint, 15 saint, 2015 saint
2_ saint » 2 saint, 21 saint, a saint

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