Operators:
- AND- This term finds items that meet both criteria. For example, cats AND dogs would find things that contained both cats and dogs
- OR- This term finds items that meet at least one of the stated criteria. For example, cats OR dogs would find things that contain cats or dogs.
- NOT- This terms finds items that meet one criteria but excludes items that meet a second criteria. The Anthropological Literature database uses the term AND NOT instead of the NOT term. It functions in the same fashion though.
Below are visual examples for AND, OR, NOT Boolean operators.
