Boolean terms are specific words you can use in a search engine to help make your search more specific. Common Boolean terms are AND, OR, and NOT. Search queries using AND will only show hits that have all the necessary words. You might use OR when looking for recipes: Chicken OR fish tacos. In the search for this question you could use NOT to also help narrow your search by searching Classic American Cars NOT Foreign. It's important that you capitalize all letters in the Boolean term, otherwise the search engine may dismiss the term as an extra unimportant word.
