Amazon's search is awful and I do not recall a time when it was better. It's probably this way by design, so that it always tends to present a never-ending stream of products to buy.

But over here in the real world where I need a specific sort of USB 3.2 widget: Either the USB 3.2 widget exists, or it does not exist. Presenting pages and pages of not-results that were already explicitly defined as irrelevant do not help a person to spend money. :)

(eBay's advanced search mode seems to still get it close-enough to right when rote specificity is important. I use it all the time to find very particular things.)
