Perhaps you should try some spelling variations:
21 bishop » 11 bishop, 128 bishop, _ bishop
2f saint » 2 saint, 25 saint, _ saint
21 saint » 1 saint, 2 saint, 25 saint
2f d » f d, 23 d, 24 d
21 d » 21 _, 1 d, 21 a

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))%((r.c bishop) OR (21 bishop)) of antioch %((((2f d) OR (21 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))%((r.c bishop) or (21 bishop)) of antioch %((((2f d) OR (21 d))) or (2 d)). ca. 110%22".
• Adding a wildcard symbol may retrieve word variants: %22ignatius %((2f saint) or (21 saint))%((r.c bishop) or (21 bishop)) of antioch %((((2f d) OR (21 d))) or (2 d)). ca. 110%22*.
