Perhaps you should try some spelling variations:
2f saint » 2 saint, 25 saint, _ saint
21 saint » 1 saint, 2 saint, 25 saint
c bishop » c bishops, _ bishop, d bishop
a bishop » _ bishop
2f d » f d, 23 d, 21 d

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: %22ignatius %((2f saint) OR (21 saint))%((2((c bishop) OR (a bishop))) OR (((c bishop) OR (a bishop)))) of antioch %((2f d) OR (2 d)). ca. 110%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22ignatius %((2f saint) or (21 saint))%((2((c bishop) OR (a bishop))) or (((c bishop) OR (a bishop)))) of antioch %((2f d) or (2 d)). ca. 110%22".
• Adding a wildcard symbol may retrieve word variants: %22ignatius %((2f saint) or (21 saint))%((2((c bishop) OR (a bishop))) or (((c bishop) OR (a bishop)))) of antioch %((2f d) or (2 d)). ca. 110%22*.
