A Boolean operator is not any of the options you provided. A Boolean operator is a term used in computer programming and search engines to combine or exclude keywords or search terms in order to narrow down or broaden search results.
There are three main Boolean operators:
1. AND: This operator is used to narrow down search results. When you use the AND operator between two keywords, the search results will only include pages that contain both of those keywords. For example, if you search for "cats AND dogs," you will only see webpages that mention both cats and dogs.
2. OR: This operator is used to broaden search results. When you use the OR operator between two keywords, the search results will include pages that contain either of those keywords. For example, if you search for "cats OR dogs," you will see webpages that mention either cats or dogs, or both.
3. NOT: This operator is used to exclude certain keywords from the search results. When you use the NOT operator before a keyword, the search results will exclude pages that contain that keyword. For example, if you search for "cats NOT dogs," you will see webpages that mention cats but do not mention dogs.
Boolean operators are helpful in refining search queries and getting more accurate and relevant search results. They can be used on search engines like Google or when searching within databases or online libraries.
To use Boolean operators effectively, you can enter your keywords in the search bar followed by the operator. For example, you can search for "cats AND dogs" or "cats OR dogs" to use the AND or OR operator, respectively.
