**Options:**

- `--url <URL>`: The URL from which to fetch data.
- `--get <GET>`: The type of data to fetch (e.g., "html", "page", "body").

**Examples:**

1. **Fetch HTML data from a URL:**

   .. code-block:: shell

      asrch fetch --url https://example.com --get html

   This command will fetch the HTML content from `https://example.com`.

2. **Fetch the body content from a URL:**

   .. code-block:: shell

      asrch fetch --url https://example.com --get body

   This command will fetch the body content of the page at `https://example.com`.

If an error occurs during the fetch operation, it will be printed to the standard error output.
