Boolean Operators are words that connect keywords together to broaden or narrow the results retrieved.
The three Boolean operators are AND, OR, and NOT.
- AND narrows your search results. Why? Because only the information that contains both words is found.
- OR expands your search results. Why? Because the information that contains one word, the other word, or both words are found.
- NOT narrows your search results. WHY? Because the results are limited to those that contain the word you wrote before NOT, but not the word after NOT.
