They may have changed it, but a few years back I did product feeds to Amazon and had to read the documentation. Basically Amazon will only search the title of the product page, nothing else.

That's why the title of the products are stupid long with everything crammed in. But yeah, you can find anything on Amazon, the site is basically broken unless you know the exact thing you want, brand, name and all.

It's not even that good at searching books anymore.
