On Amazon, sorting by anything other than "Featured" is absolutely useless. Instacart will show a couple of relevant items, and then a bunch absolutely random results, some of them being the opposite of what I asked for. A lot of that is coming from optimizing for conversion. Turns out search isn't supposed to be accurate, it is supposed to generate money. You just happen to be the minority that cares about the exact thing. Another reason is that search is just... hard. Though in Amazon's case I bet it's just sheer incompetence caused by monopoly.
