Boolean operators (the words AND, OR, and NOT) help you connect keywords and key phrases in specific ways, so you can more easily broaden or narrow your search. Using Boolean Operators takes your search to the next level and gives you more power over your search results.

Go to the final quiz.
A search using AND to connect keywords finds articles which include all the keywords in that search.
You will get fewer results, because the search will give you only that small subset!
My search soda AND coffee means I get a set of results that must include *both* keywords.
Using NOT in a search means you eliminate results with the specified word.
This is a great way to fine-tune results when you see you're getting articles that are not on topic.
My search soda NOT coffee means I get results that include:
just the word soda but not the word coffee.
The OR search looks for results with either keyword, which is really helpful when you have an initial keyword plus a great synonym.
This is a really broad search, and you will get more results!
My search soda OR coffee means I get results that include:
both soda and coffee
just have the word soda
just have the word coffee
Using parentheses helps you to build a stronger search!
Think of your keywords as sets, or combinations. Use OR to put two synonyms in parentheses, and combine that with another keyword using AND.
My search insomnia AND (soda OR coffee) means I get results that include:
insomnia, soda, coffee
insomnia, soda
insomnia, coffee
