What are Stop words?

What are Stop words?

• A. Commonly used words that are ignored in searches
• B. Words with special characters
• C. Words to start a search
• D. Keywords for indexing

Answer: (A)

Stop words are the common words that search systems typically ignore during indexing and querying to speed up processing and improve result relevance. They occur so frequently across documents (like “the,” “and,” “is,” “a,” “in”) that including them adds little discriminative value, so the engine focuses on the more meaningful terms that distinguish documents. This is why the correct choice describes stop words as commonly used words that are ignored in searches. The other options don’t fit. Words with special characters aren’t stop words—they’re a different category related to tokenization or filtering. Words to start a search isn’t a standard term for stop words. Keywords for indexing are the terms chosen to represent content; stop words are typically excluded from indexing rather than used as keywords, though some systems allow customization.
