Boolean operators are placed between your search terms fo narrow or expand a search, or to exclude such terms.

### Why this is right Boolean operators are words that set a logical relationship between search terms. They let you require multiple terms, accept alternatives, or remove results containing a term, so they can narrow, expand, or exclude search results. ### The concept A **search term** is a word or phrase you enter to find information. The common Boolean operators are `AND`, `OR`, and `NOT`. `AND` narrows a search by returning results that contain both connected terms, such as `climate AND agriculture`. `OR` expands a search by accepting either term, which is useful for synonyms, such as `teenager OR adolescent`. `NOT` excludes results containing the term that follows it, such as `jaguar NOT car`. These operators are placed between terms; quotation marks are different because they usually search for an exact phrase. ### The other options - **False**: This would be incorrect because Boolean operators do connect search terms and control which results are included. It may seem plausible if you think they are search terms themselves, but they specify how the search terms relate. ### Terms - **Boolean operator**: A word such as `AND`, `OR`, or `NOT` that tells a search system how to combine or exclude search terms. - **Search term**: A word or phrase entered into a search system to find relevant information. ### Remember Use `AND` to require terms, `OR` to allow alternatives, and `NOT` to exclude a term.
