Final answer:
'True'. The use of Boolean operators such as AND, OR, and NOT is true for refining search results by including or excluding specific search terms. They help in finding more focused and relevant information in databases or search engines.
Step-by-step explanation:
The subject of the question is related to the use of the Boolean operators for refining search results, particularly in the context of online databases or search engines. The statement suggests that for a more accurate search, you should limit a term to a specific search field, which is generally true. Boolean operators like AND, OR, and NOT can significantly refine search outcomes.
When you use AND, the search results will include all items that contain every term you're linking together. A search with the string "ethics AND artificial intelligence" will yield results that include both terms, thereby narrowing the search and providing more focused results.
