Perhaps you should try some spelling variations:
2015 saint » 2013 saint, 2015 san, 2015 joint
25 saint » 15 saint, 25 saving, 25 saying
21 saint » 1 saint, 2 saint, 2013 saint
c bishop » c bishops, _ bishop, a bishop
5 saint » 5 saints, 1 saint, 2 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 %((((_ saint) OR (((((25 saint) OR (2015 saint))) OR (5 saint))))) OR (21 saint))%c bishop of smyrna%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22polycarp %((((_ saint) or (((((25 saint) OR (2015 saint))) or (5 saint))))) or (21 saint))%c bishop of smyrna%22".
• Adding a wildcard symbol may retrieve word variants: %22polycarp %((((_ saint) or (((((25 saint) OR (2015 saint))) or (5 saint))))) or (21 saint))%c bishop of smyrna%22*.
