Google Dorking, Also known as “Google hacking,” involves using specialized search parameters to locate very specific information. Examples include:

» (U) Site: Searches and lists all the results for that particular site.
» (U) Intext: Searches for the occurrences of keywords all at  once or one at a time.
» (U) Inurl: Searches for a URL matching one of the keywords
