Google hacking is a way of using search operators to narrows the list of results during a google search. This is not anything new and has been round for a long time and is indeed a powerful tool. The process involves using advanced operators to fine-tune your results to get what you want instead of being left at the whim of the search engine. With google hacking it is possible to manipulate the result in such a way that it enables you to obtain items such as passwords, certain file types, sensitive folders, logon portals, configuration data, SQL dumps, and a lot of specific things.
The search operators is entered directly into the search box on the google search web page. The operators seems to work best if they are allowed to go before any other normal search strings.
