My guess is that it’s trying to be helpful – that if you (for example) type in a search for lucy and wardrobe and cordial it doesn’t limit it to all of those things, but shows you everything.

Which is fine if you are new to the web, but if you do know what you want and are looking for the exact thing, then ten thousand results…

I can see what they were doing ignoring the operators, but yeah – it blows.
