Perhaps you should try some spelling variations:
2c bishop » c bishop, 21 bishop, r.c bishop
2f saint » 25 saint, de saint, a saint
2_ saint » 25 saint, de saint, a saint
21 saint » 1 saint, 25 saint, 2013 saint
2 saint » 2 saints, 1 saint, 5 saint

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

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