In Module 1, Unit 1, you learnt
the basics about the Internet and searching. You were given an opportunity to complete a basic activity on searching the WWW. In this unit you are going to build on this knowledge by developing an understanding of Boolean logic and the way in which it can be used to refine searching skills and techniques.

The best way to refine your searching skills and techniques is to ensure that you understand the basics of Boolean logic. Take some time to understand the basics by reading through the resources below.

Boolean Logic
'The Internet is a vast computer database. As such, its contents must be searched according to the rules of computer database searching. Much database searching is based on the principles of Boolean logic. Boolean logic refers to the logical relationship among search terms, and is named for the British-born Irish mathematician George Boole. On Internet search engines, the options for constructing logical relationships among search terms often modify the traditional practice of Boolean searching.' (Ref: Cohen 2011)
