Perhaps you should try some spelling variations:
r.c bishop » f.r.s bishop
2f saint » 2 saint, 21 saint, a saint
25 saint » 5 saint, 15 saint, 2015 saint
16 saint » 18 saint, 14 saint, 15 saint
10 saint » 10 saints, 18 saint, 14 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 (((25 saint) OR (((16 saint) OR (10 saint))))))) OR (((1 saint) OR (_ saint))))%r.c bishop of smyrna%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22polycarp %((((2f saint) or (((25 saint) or (((16 saint) or (10 saint))))))) or (((1 saint) OR (_ saint))))%r.c bishop of smyrna%22".
• Adding a wildcard symbol may retrieve word variants: %22polycarp %((((2f saint) or (((25 saint) or (((16 saint) or (10 saint))))))) or (((1 saint) OR (_ saint))))%r.c bishop of smyrna%22*.
