Stop words are best described as what in search systems?

• A. They refine search results by boosting matching terms
• B. They are ignored during search queries
• C. They determine result order by date
• D. They trigger alerts when found

Answer: (B)

Stop words are common words that search engines typically remove before searching or indexing. They include articles and short prepositions like the, and, of, to, is. This helps speed up searches and reduce index size because these words seldom help distinguish one document from another. When you type a query, the system often filters these words out so the search focuses on the meaningful terms. In some cases stop words may be treated specially in phrase searches, but in standard behavior they are ignored, which is why this description fits best. The other options describe boosting terms, ordering results by date, or triggering alerts, which aren’t the role of stop words.
