I try the demo code to download news text.However,no matter How long I set the time period for searching of crude oil news,there only returns 10 results .I guess its the parameter problem.How can I get more news texts?
df = ek.get_news_headlines('Crude', date_from='2019-03-21T09:00:00', date_to='2020-03-21T18:00:00')
