Learn to Search QCAT:
What are Boolean operators? George Boole was an English mathematician. He invented a method of symbolically representing relationships between sets using the operators AND, OR, and NOT.
Why are these operators important? When you type words into a library index, you need to connect them according to the rules for that index. Many indexes require the use of Boolean operators to express your search words in a form that the computer can interpret.
