Google Dorks

Google Dorks


Google!!!
One of the most used search engine of all time. Problems to our all solution is to "Google up everything" or what is now popularly called as "Googling" . We use google for almost everything, it has now become an integral part of our life. 
But do you know how to use it efficiently,sometime you want to search for something and messed up with clicking on everylink that appears on the search result. And even after searching for hours you don't get satifactory result.
That was what you used to do before, from now you will probably be using google dorks for fast and efficient search.
For eg.  okay lets suppose that you wanna search for ebooks on topic 'networking' , our obvious search queries would be like this "Networking ebooks", "free ebooks for networking" etc,we keep going into the websites, clicking on link after links and then get proper downling links. Now lets do the same search in a different way , type on google "ext:pdf networking" (without quotes). So how about that, impressed yet.!!
