How big is the sun?
YahooYahoo gives me an interesting alternate query. The links are all relevant too.
BingBing starts well by suggesting some queries.
But, it soon falls apart IMO.
Big Red Sun? A garden design company? That is the most relevant? Really? The third result is way off too. Their related searches clearly seem to indicate that Bing understands what I am looking for, but their results fail badly. Get the log out of your eye Bing.
