Boolean Operators
Boolean Operators is a term for words and symbols that are used to connect keywords when searching for information. These words and symbols can either broaden or narrow your search, which means you retrieve results that are relevant and effective - saving you precious time.

HOW IT AFFECTS YOUR SEARCH RESULTS |
EXAMPLES USING THE KEYWORDS 'CHOCOLATE' AND 'DESSERT' |
---|---|---|
AND | Retrieved results include all keywords used | Chocolate AND Dessert = will retrieve all results that include both chocolate and dessert |
OR | Retrieved results only include either one keyword, but not both | Chocolate OR Dessert = will retrieve all results that include chocolate or dessert, but won't include results where chocolate and dessert appear together |
NOT | Retrieved results include the first word, but not the second word | Chocolate NOT dessert = will retrieve all results that include chocolate, but will not include any results that include dessert |
( ) parenthesis |
Keywords included inside the brackets are grouped together in a single search, allowing you to control the order the words are searched in. This is especially useful when you are using more than one Boolean operator during the same search. |
(Chocolate dessert)
Another example is: |
" " quotation marks |
Keywords that are included inside quotation masks retrieve results as an exact match |
"chocolate dessert"

TRUNCATION & WILDCARD OPERATORS |
