Perhaps you should try some spelling variations:
21 sermons » 2 sermons, 1 sermons, 6 sermons
25 matthew » 15 matthew, 2 matthew, 22 matthew
2f matthew » 2 matthew, 22 matthew, _ matthew
2.1 early » 11 early
1.1 early » 11 early, 1791 early, 1771 early
20 51 » 20 21, 24 51, 20 5
2c 51 » 24 51, c 51, 21 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) OR (25 matthew)) xxviii%((2c 51) OR (20 51)) %21 sermons %((1.1 early) OR (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) or (25 matthew)) xxviii%((2c 51) OR (20 51)) %21 sermons %((1.1 early) or (2.1 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %((2f matthew) or (25 matthew)) xxviii%((2c 51) OR (20 51)) %21 sermons %((1.1 early) or (2.1 early)) works to 1800%22*.
