Fess también incluye un rastreador (crawler), que puede rastrear documentos en un [servidor web](https://fess.codelibs.org/14.17/admin/webconfig-guide.html), [sistema de archivos](https://fess.codelibs.org/14.17/admin/fileconfig-guide.html), o [almacenamiento de datos](https://fess.codelibs.org/14.17/admin/dataconfig-guide.html)...

#       The "traditional" practice of packing multiple parameters into a
#       space-separated string is a well documented source of bugs and security
#       problems, so this is (mostly) avoided, by progressively accumulating
#       options in "$@", and eventually passing that to Java.

* A `skip` query parameter that is an `int`, with a default of `0`.
* A `limit` query parameter that is an `int`, with a default of `100`.

In both cases the data will be converted, validated, documented on the OpenAPI schema, etc.

## Use it

Now you can declare your dependency using this class.

```Python hl_lines="19"

        public String propertiesPath;

        @Option(name = "-e", aliases = "--expires", metaVar = "expires", usage = "Expires for documents")
        public String expires;

        @Option(name = "-h", aliases = "--hotThread", metaVar = "hotThread", usage = "Interval for Hot Thread logging")
        public Integer hotThread;

MINIO_ETCD_CLIENT_CERT_KEY  (path)      client cert key for mTLS authentication
MINIO_ETCD_COMMENT          (sentence)  optionally add a comment to this setting
```

This behavior is consistent across all keys; each key self-documents itself with valid examples.

## Dynamic systems without restarting server

Il effectue également la validation des données (même imbriquées les unes dans les autres), et permet de les documenter correctement (schéma OpenAPI et documentation auto-générée).
