Which search method uses logical operators such as AND, OR, NOT to combine search terms?

• A. Boolean search
• B. Keyword search
• C. Natural language search
• D. Proximity search

Answer: (A)

Using logical operators to combine search terms is how Boolean search works. In this method you connect terms with AND, OR, and NOT to control exactly which results appear. AND requires both terms to be present, narrowing the results; OR broadens the results by including either term; NOT excludes terms you don’t want. For example, searching for cats AND dogs will return pages that mention both terms, while cats OR dogs will return pages that mention either one, and education NOT college will omit pages that mention college. You can also group terms with parentheses to set the order of operations, like (education OR learning) AND technology, to refine the focus further. This approach is distinct from other search methods: a keyword search looks for the words themselves without defined relationships; a natural language search interprets a user’s full sentence or question; a proximity search looks for terms that appear close to each other, often with a specific distance. Boolean search is the best fit for precisely combining terms with those logical operators.
