21 bishop » 11 bishop, 128 bishop, a bishop
2c bishop » r.c bishop, 128 bishop, m.c bishop
25 saint » 5 saint, 15 saint, 2015 saint
21 saint » 2 saint, 2013 saint, 2015 saint
c bishop » c bishops, a bishop, d bishop

• If you are trying to use Boolean operators, they must be ALL CAPS: %22polycarp %((((25 saint) OR (1 saint))) OR (21 saint))%((((2c bishop) OR (c 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 (1 saint))) or (21 saint))%((((2c bishop) OR (c bishop))) or (((21 bishop) or (_ bishop)))) of smyrna%22".
• Adding a wildcard symbol may retrieve word variants: %22polycarp %((((25 saint) or (1 saint))) or (21 saint))%((((2c bishop) OR (c bishop))) or (((21 bishop) or (_ bishop)))) of smyrna%22*.
