Note: I personally ran the same searches and didn’t have nearly as many of the searches return “no results” but I did get a few.

From The Federalist:

On Twitter early this morning, Ryan Fitz flagged something weird: Google Shopping returns no results for any search containing the word “gun.”

Nothing with “gun” in it gets any Google Shopping results, not even if part of another unrelated word. Try it. pic.twitter.com/rUc87l3fkD
