Explanation:

Search engines or internet browsers are programs, software or similar that allows you to look for information on the internet or in a specific database, that provides you with results mainly based on the words you type to look for the information although other factors such as location, preferences and previous searches might have an influence. This means search engines focus on the main words you type and the way you connect those using using coordinating conjunctions such as "and, or, but, not" in case you are using more than one term or word, for example the word "not and but" will exclude some results but the word "and" would look for documents or pages in which both terms appear.

Considering this, if Deepak wants to find information from famous World War II pilots but only wants to focus on the United States pilots and not the German ones the search that will give her the results she wants is "United States pilots not German pilots in World War II" as this search include the key terms which are "United States pilots ... in World War II" but excludes the information Deepak does not want by using the word "not" which is "German Pilots.
