Pretty much every major shopping website has terrible search functionality.

I usually want something very specific, for example 60w dimmable e12 frosted warm led bulb. I have not found a single shopping website that won’t show me results without many of these terms in the description. I don’t want to see listings that say 40w and don’t say 60w anywhere, and it isn’t hard to filter them out!

Are these shopping websites bad on purpose? What’s in it for them?
