Here’s an example of a Google or Bing query that you can use to list Microsoft Knowledge Base articles that were added or updated on a given day (August 28, 2017 in this example):
+”aug 28 2017″ site:support.microsoft.com/en-us
The month should always contain the first 3 letters of the month that you are searching for.
I recommend using both Google and Bing because a given search engine doesn’t necessarily find everything that is relevant.
