When might a user consider using a Boolean search in a search engine?

• A. The user wants the most relevant websites to be listed at the top of the results page.
• B. The user wants to allow for variations in spelling or word forms.
• C. The user wants to eliminate any results that contain a specific term.
• D. The user wants only documents in which chosen words appear side by side.

Answer: (C)

Using a Boolean search is particularly beneficial when a user wants to refine their search results and focus on specific criteria. When a user aims to eliminate any results containing a specific term, a Boolean search allows the inclusion of operators such as "NOT," which enables them to exclude certain words from the search. This can significantly enhance the relevancy of the results by filtering out unwanted content that may otherwise skew the search outcome. For instance, if a user is searching for information about healthy eating but wants to exclude results that mention "fast food," they would use a Boolean operator to accomplish this. This targeted approach ensures the user receives a more efficient and relevant set of search results based on their unique requirements.
