Which of the following terms refers to operators used in searching?

The term that refers to operators used in searching is commonly known as Boolean operators. These operators, which include "AND," "OR," and "NOT," are foundational in search logic and are used to refine search queries in databases and search engines. By applying Boolean operators, users can create complex queries that improve the precision of search results. For example, using "AND" between two keywords will return results that contain both terms, while "OR" will return results that contain either term, and "NOT" will exclude specific terms from the search results.

The other options, while related to searching, do not specifically capture the essence of operators used in constructing searches. "Search modifiers" can refer to various techniques or symbols that adjust search parameters, but they are not specifically the operators themselves. "Keyword filters" typically help narrow down results based on specific terms or phrases but do not define the logical operation between those terms. Lastly, "data parameters" refer to the values or criteria set for retrieving data but again do not denote the operators that dictate how the terms are combined in searching. Therefore, Boolean operators is the most accurate and widely used term for discussing the operators involved in search queries.
