Make a decision using Search Engine - is it possible?

The recent presenting of Bing as a Search Engine for making decision brings up such a question as it is possible to make decisions using Search Engines as this point at all?

The real life data about using Search Engines tells us that there are 3 major types of search - navigational, commercial and informational. Let's review each of them in an attempt to answer the question I put in this post title.

• Navigational search. In a nuts shell it's about typing a website domain name as keyword when you aren't sure if you spell it correctly. With the veracity of domain names it's no wonder that people do that type of search. But certainly this kind of search doesn't lead a person to make a decision. You are already know what you gonna do when you type a domain name.
• Commercial search. These days more and more people do make a decision to purchase something based on what they read about this product or service on the Internet. Let's say I want to buy a new LCD monitor (the matter fact I do:-) ) and before going into a store and asking questions to a seller, who basically can't be objective, I turn on my Macbook, go online and start googling this product.

But wait - I don't use Google for finding information about which LCD to buy, I use for this purpose Cnet.com - in a sense, a vertical Search engine for making purchase decisions. Now this is just a one example, there are tons of products and services we purchase and sure enough - there isn't 'Cnet.com' for every single of them. You simply can't create a vertical, means dedicated to specific product or service, Search Engine for all stuff you need either purchase or sale.

So the idea to equip a regular Search Engine like Google or Bing with vertical SE abilities is an important and logical one. And Google, Bing, Ask already have so-called Shopping search function. The bottom line is at this point we can make decisions using Search Engines when it comes to shopping.

• Informational search. And this is the hardest part. When you think about an example of searching for information it's really hard to come up with the one as there are so-o-o many kinds of info we need daily and I don't think that any algorithm is capable of allowing a person to make decisions about info they look for using Search Engines. Quite frankly the day when a Search Engine will allow you to make a decision about information you look for is the one when artificial intelligent becomes reality.
