Quizplus · Accepted Answer

A Boolean operator is a term used in electronic database searching to describe the relationships between keywords or phrases. The most common Boolean operators are "AND," "OR," and "NOT." These operators are used to refine or expand a search by specifying the relationships between the search terms.
For example, if a nurse wanted to search for articles on the effectiveness of both medication and cognitive-behavioral therapy for the treatment of depression, they could use the "AND" operator to connect the terms "medication" and "cognitive-behavioral therapy." This would result in a more specific search, limited to articles that include both of these terms.
Understanding how to use Boolean operators can help nurses and other healthcare professionals perform more efficient and effective literature searches, saving time and ensuring that they find the most relevant and useful articles on a particular topic.
