What is a Boolean Operator used to do in search?

• A. Combine keywords using and, or, and not to refine search results.
• B. List all search results from the database.
• C. Filter results by publication date only.
• D. Randomize search results to avoid bias.

Answer: (A)

Boolean operators are the logical tools you use when searching to connect and relate keywords. They let you control how the terms in your query interact, so you can refine what shows up. The key idea is to combine keywords using and, or, and not to shape the results. And narrows the results by requiring both terms to appear, or broadens them by allowing either term, while not excludes a term to filter out unwanted results. For example, searching for cats AND dogs returns items containing both words; cats OR dogs returns items containing either word; cats NOT dogs excludes items that mention dogs. The other options describe actions like listing all results, filtering only by date, or randomizing results, which are not what Boolean operators themselves do.
