The Boolean search operator "OR" is often used with these terms: A. antonyms B. homonyms C. synonyms

The Boolean search operator "OR" is primarily used with C. synonyms. This operator allows you to widen your search results by including either one term or another. For example, if you are searching for articles related to "car" OR "automobile," the search will return results that contain either of these words.

Using "OR" with synonyms helps in finding related information that may be expressed in different terms but conveys the same or similar meaning. On the other hand, using it with antonyms or homonyms may lead to less relevant search outcomes. Thus, the use of "OR" is particularly effective when searching for variations of a term to gather comprehensive information.
