• If you are trying to use Boolean operators, they must be ALL CAPS: %22bible %2f n.t %((((2f matthew) OR (22 matthew))) OR (25 matthew)) xxviii%24 51 %((2f sermons) OR (21 sermons)) %((2.1 early) OR (((11 early) OR (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 (22 matthew))) or (25 matthew)) xxviii%24 51 %((2f sermons) OR (21 sermons)) %((2.1 early) or (((11 early) or (1 early)))) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %((((2f matthew) or (22 matthew))) or (25 matthew)) xxviii%24 51 %((2f sermons) OR (21 sermons)) %((2.1 early) or (((11 early) or (1 early)))) works to 1800%22*.
