Boolean queries

Boolean queries are a way to refine search results using specific operators: AND, OR, and NOT. When you combine keywords with these operators, you can narrow or broaden your search. For example, "cats AND dogs" finds results that include both terms, "cats OR dogs" finds results with either term, and "cats NOT dogs" excludes results that mention dogs. This method helps you retrieve more relevant information by clearly defining your search criteria, making it easier to find what you’re looking for in databases, search engines, or library catalogs.
