Google search cannot search for news articles in the last 24 hours when using filters anymore. You can easily see that it includes results from last year or even before that and bogus pages that aren't news. I also can't remove certain sites, I want only sites with .edu. This link worked yesterday, but Google decided to not support the site: operator anymore when searching for news.
I am not sure why, but Google has become absolutely terrible and I am trying to find alternatives, because they removed a lot of features and it seems like sometimes 90% of the results are missing.
