• If you are trying to use Boolean operators, they must be ALL CAPS: %22hymns%((((21 english) OR (1 english))) OR (((2017 english) OR (10 english)))) %((2f texts) OR (20 tests))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22hymns%((((21 english) OR (1 english))) or (((2017 english) or (10 english)))) %((2f texts) or (20 tests))%22".
• Adding a wildcard symbol may retrieve word variants: %22hymns%((((21 english) OR (1 english))) or (((2017 english) or (10 english)))) %((2f texts) or (20 tests))%22*.
