Hello,
I checked and at the moment there are no news indexed by the API which come from Google News which contains also the keyword cardano. I will check on this and make the plugin import more articles from this news source.
Until then, I recommend that you select another source and import content from it or change the keyword you are using the query news from Google News.
Also, please note that simply using the keyword cardano will be enough to query articles which contain this specific keyword.
