Test, validate and match regular expressions
This regex matches the literal string 'Hund' (German for 'dog') anywhere it appears in the input text. It contains no metacharacters or special syntax, so it performs a simple case-sensitive substring search. It is useful for finding mentions of dogs in German text, though it will not match variations like the plural 'Hunde' or lowercase 'hund' unless case-insensitive matching (e.g., the /i flag) is enabled.
