What term describes the use of modifiers such as AND and OR in text searches?

The correct term that describes the use of modifiers like AND and OR in text searches is Boolean operators. These operators are fundamental in constructing search queries that help in refining and specifying the attributes of the search results.

Boolean operators facilitate advanced searching techniques, allowing users to combine or exclude keywords effectively. For instance, using "AND" narrows the search by ensuring that all specified terms must be present in the results, while "OR" broadens it by allowing for the presence of either term. This capability is essential in investigations and research contexts where precise and relevant information is crucial.

The other terms might relate to various types of computing or search operations but do not precisely capture the mechanism of combining search terms as Boolean operators do. This specificity makes Boolean operators the most accurate choice in the context of text searches.
