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 xxviii) OR (matthew xiii))%2c 51 %2f sermons %((21 early) OR (((2.1 early) OR (((1.1 early) OR (11 early)))))) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %2f ((matthew xxviii) or (matthew xiii))%2c 51 %2f sermons %((21 early) or (((2.1 early) or (((1.1 early) OR (11 early)))))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %2f ((matthew xxviii) or (matthew xiii))%2c 51 %2f sermons %((21 early) or (((2.1 early) or (((1.1 early) OR (11 early)))))) works to 1800%22*.
