If it fails to provide you with relevant results for your search, Google will send you an alert.
Google wants to prevent the spread of Fake News, and they developed a new Search feature called About this Result, this is the first step towards detecting misleading news.
When you search for something without verifying the facts, Google will send a warning that your search is not relevant and that it is most likely untrue news or an unreliable source of information.
There are many unproven claims and there are a large number of opinions about them, which often change.
When a new topic appears, Google will immediately notify you that the facts about it have not been verified and will send you a warning not to take everything for granted.
Here is a good Chrome extension for the prevention of fake news: FakerFact: Fake News Detection
This extension will open up a new tab on fakerfact.org to check your current tab’s content for indications of fake news.
