## Adicionando expressões regulares

Você pode definir uma <abbr title="Uma expressão regular, regex ou regexp é uma sequência de caracteres que define um parâmetro de busca para textos.">expressão regular</abbr> que combine com um padrão esperado pelo parâmetro:

```Python hl_lines="11"
{!../../docs_src/query_params_str_validations/tutorial004.py!}
```

Essa expressão regular específica verifica se o valor recebido no parâmetro:

	c.Minio.Release = ""
	crc := hashDeterministicString(c.Meta)
	c.Meta = nil

	if bts, err := c.MarshalMsg(metaDataPoolGet()); err == nil {
		crc ^= xxhash.Sum64(bts)
		metaDataPoolPut(bts)
	}

	// Combine upper and lower part
	var tmp [4]byte
	binary.LittleEndian.PutUint32(tmp[:], uint32(crc^(crc>>32)))
	return tmp
}

// XL metadata constants.
const (
	// XL meta version.
	xlMetaVersion101 = "1.0.1"

    ImmutableSet.Builder<String> zis = ImmutableSet.<String>builder().add("a", "b", "a");
    ImmutableSet.Builder<String> zat = ImmutableSet.<String>builder().add("c", "b", "d", "c");
    ImmutableSet<String> set = zis.combine(zat).build();
    assertThat(set).containsExactly("a", "b", "c", "d").inOrder();
  }

  @Override
  <E extends Comparable<E>> Builder<E> builder() {
    return ImmutableSet.builder();
  }

  @Override
