In search terminology, what does the operator 'NOT' do?

The operator 'NOT' is used in search terminology to exclude specific terms from search results. When a user incorporates 'NOT' followed by a term in a search query, it instructs the search engine or database to filter out any results containing the excluded term. This can help refine search results by eliminating unwanted or irrelevant content.

For example, if a user is searching for articles on healthy diets but wants to avoid any mentions of a specific type of diet, they would use 'NOT' to exclude that term, ensuring relevant results focus on their topic of interest without the distraction of the excluded information. By using this operator effectively, users can enhance the precision of their searches and find more pertinent information.
