Finally, Amazon's marketplace is just not navigable. Their search is pathetically bad, and this is nothing new, it's been a common complaint for years. Some fairly massive amount of their traffic is inbound from Google searches like "some product amazon" just because of how pathetically bad it is. The only other reasonable way to navigate their site is if their similar product suggestions or "commonly bought together" happens to nail the item you were looking for.
I've had searches where adding an additional keyword that is in the product title will actually cause the product to disappear from the search. What in the actual fuck.
