Boolean Search is a method used in information retrieval that employs specific operators to refine search results. The primary operators are AND, OR, and NOT, which help users combine or exclude keywords. For example, using AND narrows the search by requiring both terms to be present, while OR broadens it by including results that contain either term. This technique is commonly used in databases, search engines, and libraries to enhance the accuracy of search results. By utilizing Boolean operators, users can effectively filter through large amounts of data, making it easier to find relevant information quickly.
