Final answer:
Use the Boolean operator NOT to exclude certain results from your search, helping to narrow down the information and omit unwanted terms.
Step-by-step explanation:
To exclude certain results from your search, you should use the Boolean operator NOT. This operator is beneficial for narrowing your search by telling the search engine to omit any information or results that contain the specified terms you do not want to include. For instance, if you are researching "artificial intelligence" but wish to exclude any results related to "self-driving cars", you would use the query: "artificial intelligence" NOT "self-driving cars". Understanding how to use Boolean operators such as AND, OR, and NOT helps in linking necessary information, focusing your searches, and most importantly, excluding irrelevant information.
