Which search approach uses operators to refine results?

• A. Boolean search
• B. Keyword search
• C. Free text search
• D. Fielded search

Answer: (A)

Refining results through logical relationships is what a Boolean search does. In this approach, you connect your search terms with operators such as AND, OR, and NOT to control how the terms relate to each other. Using AND narrows results by requiring both terms to appear; OR broadens results by allowing either term; NOT excludes items containing a term. This kind of explicit control over what must or must not be included makes searches more precise and efficient, especially when you need to filter out irrelevant material or combine several concepts. Other approaches rely on listing terms without formal operators, or on searching within specific fields, which don’t provide the same level of logical refinement.
