Combining Your Keywords: Boolean Operators
Boolean operators are the words AND, OR, and NOT. These words connect keywords, allowing you to define the relationships between keywords and get the results you want.
|OPERATOR||WHAT IT DOES||EXAMPLES|
Placing AND between two keywords requires that any results you find contain BOTH keywords. The AND is used to narrow your search. Use it to connect two ideas that both need to be in the results you find.
|OR||The OR lets you search for either keyword at the same time. Use it when you have multiple keywords that are synonyms.||
|NOT||The NOT operator excludes specific keywords. Be careful when using NOT: removing a keyword from your search results may eliminate useful comparison articles.||
