3.2 Searching with Boolean operators

AND

The AND-operator is used to connect two or more search terms/concepts

 

 

 

OR

The OR-operator is used for synonyms, related terms, plural/single and different ways of spelling

 

Note: Use of parentheses (round brackets) is required when using the OR-operator.

 

NOT

The NOT-operator is used to exclude search terms/concepts

 

Note: Be careful when using the NOT-operator! You may unintentionally exclude relevant documents from your results!
