Fun example: there is an issue with Amazon grocery search where it will tell you that they are out of a very common item, such as bananas, but when you check out it will suggest that you add bananas. You can also add the allegedly out of stock items by going to your previous items page. Just bizarre.

And it happens even if there is a good number of relevant products. I've searched for something like "[brandname] 12v fridge" and had a few [brandname] results mixed in amongst countless other random brands. If I'm searching for a specific brandname, that's exactly what I want!

Yea this is super frustrating. Rarely the actual brand name product does not show up until like the second page if its something without a lot of reviews or popularity. And it does not seem like they allow any types of "advanced" search...
