Which statement best describes how a Boolean search operator can be used?

• A. Use quotes to require an exact phrase
• B. Use a wildcard to substitute for unknown characters
• C. Use NOT operator to exclude terms
• D. Use a date range to limit results by time

Answer: (C)

In Boolean searching, using NOT to exclude terms is the most direct way a Boolean operator refines results. The NOT operator tells the search system to omit any documents that contain a specific word, which helps you narrow the results to only what you want. For example, if you’re researching dogs but want to exclude beagles, you could search for dogs NOT beagle. This clearly demonstrates how a Boolean operator trims your results by removing unwanted terms. The other options describe useful search techniques, but they’re not Boolean operators in the same sense. Quotation marks are for exact phrase matching, which keeps a sequence of words together. Wildcards substitute unknown characters within a term to broaden matches. A date range limits results by time, which is a filtering parameter rather than a Boolean operator used to exclude or combine terms. So, excluding terms with the NOT operator best illustrates how a Boolean operator can shape search results.
