Google is Testing an Update Button to Refresh the Search Results

Search Engine Roundtable published the post that Google had tested the Update button, which allows the users to get the latest search results.

Google tested a similar feature in summer, 2018. However, the design of the button was different:

During the previous testing, the new function activated if the user did not interact with the search results for some time, and then returned to them. With the Get Latest button, you could see the results appeared during this time.
