Qwant now requires a `datadome` cookie that it returns
in the first search response as a `Set-Cookie`.
This cookie has to be sent for all requests, otherwise they
will be blocked.
This means that now, the first search request is blocked (results in CAPTCHA),
and only the subsequent searches work (same happens on the Qwant website for me).
However, I don't think it's worth repeating the same
search request multiple times very quickly because
that also makes us more suspicious.
