Perhaps you should try some spelling variations:
r.c bishop » f.r.s bishop
2c bishop » 128 bishop, m.c bishop, _ bishop
21 bishop » 11 bishop, 128 bishop, _ bishop
25 saint » 5 saint, 15 saint, 2015 saint
21 saint » 1 saint, 2 saint, 2013 saint
2f d » 2 d, f d, 23 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 %((25 saint) OR (21 saint))%((((2c bishop) OR (r.c bishop))) OR (21 bishop)) of antioch %2f d. ca. 110%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22ignatius %((25 saint) or (21 saint))%((((2c bishop) OR (r.c bishop))) or (21 bishop)) of antioch %2f d. ca. 110%22".
• Adding a wildcard symbol may retrieve word variants: %22ignatius %((25 saint) or (21 saint))%((((2c bishop) OR (r.c bishop))) or (21 bishop)) of antioch %2f d. ca. 110%22*.
