Searching on the Web

Chirs Nolan's presentation of different ways to look and search for information was interesting because he discussed and presented new and effective ways of looking through google. It was pretty amazing for me to realize that nearly 80% of the information published in the web do not appear when you look for it because of the password restrictions. Moreover, it was really interesting to find out the ranking that google uses to show what you look for. I was informed that sponsored links, and how frequent any webpage is linked to other webpages are used to rank appearances when looking for information in google.
I was pretty amazed as well to learn how to look for definitions. I had no idea that if you write a word with quotation marks then the search will take you to the direct definition of the word. As well as this, I was surprised to see that the "I'm feeling lucky" option actually takes you directly to the first option of wbsites listed for you in any search.
When I thought there could be no more advantages by using google as a searcher, I was surprised with the fact that you can look just for scholarly articles and information rather than just random articles.
Definitely google is a useful tool that has many more advantages that I was not aware of. Now I understand why google is creating such a difference in people's life that even it is starting to be used as a verb!
