Perhaps you should try some spelling variations:
2f sermons » 21 sermons, 24 sermons, 20 sermons
2f matthew » 2 matthew, 22 matthew, 25 matthew
2.1 early » 1.1 early, 11 early
2c 51 » 24 51, c 51, 21 51
20 51 » 290 51, 20 21, 24 51

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: %22bible %2f n.t %2f matthew xxv%((2c 51) OR (20 51)) %((2f sermons) OR (2 sermons)) %2.1 early works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %2f matthew xxv%((2c 51) or (20 51)) %((2f sermons) OR (2 sermons)) %2.1 early works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %2f matthew xxv%((2c 51) or (20 51)) %((2f sermons) OR (2 sermons)) %2.1 early works to 1800%22*.
