Perhaps you should try some spelling variations:
21 english » 210 english, 2 english, 1 english
2f texts » _ texts, ii texts, i texts
20 texts » _ texts, ii texts, i texts
20 tests » 10 tests, 20 test, 20 teeth
2 texts » _ texts, 2 texte, i texts

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