Perhaps you should try some spelling variations:
21 english » 210 english, 1 english, 11 english
2f texts » _ texts, 8 texts, a texts
20 texts » 20 tests, _ texts, 20 teeth
3 texts » _ texts, 3 text, 3 texte
1 texts » _ texts, 1 text
2 texts » _ texts, 2 text, 2 texte

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: %22hymns%((21 english) OR (2 english)) %((((((2f texts) OR (((3 texts) OR (1 texts))))) OR (2 texts))) OR (20 texts))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22hymns%((21 english) or (2 english)) %((((((2f texts) or (((3 texts) OR (1 texts))))) or (2 texts))) or (20 texts))%22".
• Adding a wildcard symbol may retrieve word variants: %22hymns%((21 english) or (2 english)) %((((((2f texts) or (((3 texts) OR (1 texts))))) or (2 texts))) or (20 texts))%22*.
