What is a key benefit of using Boolean logic in database searches?

Using Boolean logic in database searches enhances the precision of the results. This logic allows users to combine keywords with operators such as AND, OR, and NOT, thereby creating more complex and targeted search queries. For instance, employing the AND operator narrows down results by ensuring that all specified terms are present, while OR broadens results to include any of the listed terms. Meanwhile, NOT excludes certain terms, helping to refine the search further. As a result, the application of Boolean logic effectively filters results more accurately, yielding a set of results that closely align with the user's research needs and objectives. This precision is crucial in evidence-based practice, where the relevance and validity of the information being sought are paramount.
