Sounds like you aren't using the right keywords.
Oh, I see. There is a misunderstanding because Bing is a search engine. What I was referring to is a promotion by Microsoft to use Bing for searches. Just for giggles I signed up and used Bing off and on. I keep getting these promotional emails with all these pictures and mumbo jumbo. One of the promotions had a bunch of prizes and you were supposed to pick your goal. I figured I would select something very mundane and attainable. Just to see what would happen. I picked a free coffee at Starbucks. That was several months ago. I have been unable to ascertain from any of the subsequent communications if I am close to or light years away from this magnificent reward.
I don't link a lawyer could decipher this stuff. It is all marketing hype-speak. Lots of pictures and no information. I just assume that I will never get my coffee. I would rather pay $10 for a coffee than do all the work needed to figure out if there is any real information in any of this stuff I get from them. I think a lot of other people do the same. It is probably psychologically engineered to get people to set Bing as default search engine, then give up in disgust when they receive all the ads. But I am sure a certain percentage don't bother to set the engine back to Google. That's how they getcha'!!
