Which search engine is better?

Which is a better search engine: Bing, Google, Blekko or Yahoo?

• It's undeniable that the world's most popular search engine is Google but a personal research has proven that popularity doesn't signify being best among others. To the point, I pasted a 40-page document in the search box of the above  search engines in an attempt to test the intelligence of today's admired creation and the results were as follows: 1. Google: 413. That's an error. Your client issued a request that was too large. That's all we know. 2. Yahoo!: Sorry, Request-URI Too Large. The requested URL's length exceeds the capacity limit for the server. request failed. URI too long. 3. Blekko: 414 Request-URI Too Large. 4. Bing: Quite incredible, Bing returns the exact same document from the Internet. From my research, one can deduce that Bing is the most powerful and reliable search engine of the 21st century.

• Answer:

  Google will help you well when you have a slow internet connection and need something really urgent. No frills and all, just a simple guy. However, Bing is simply superb in image search, perhaps the best you can get. I don't say the text search is bad yet its upto you to choose.
