What is a query (information retrieval)?

• A. A shelving strategy.
• B. The question or search terms a user enters into an information system to find relevant information.
• C. A type of library card.
• D. A list of recommended books.

Answer: (B)

A query in information retrieval is the words or question a user enters into a search system to locate information. It is the input that drives the retrieval process, translating your information need into terms the system can match against titles, authors, subjects, and keywords in its index. The system uses your query to find and rank items that best satisfy what you’re looking for, often allowing refinements like exact phrases, synonyms, or Boolean operators to fine-tune results. A shelving strategy is about how physical materials are organized on shelves, a library card is used to borrow materials, and a list of recommended books is a reading suggestions list—none of these describe the input you use to search the library or database.
