Which of the following situations might prompt a user to consider a Boolean search while seeking information in a search engine?

A Boolean search is characterized by the use of logical operators such as AND, OR, and NOT to refine search results. In this context, when a user wants to eliminate any results that contain a specific term, using the NOT operator in a Boolean search is the perfect strategy. This allows the user to filter out unwanted results and focus on more relevant content. For instance, if a user is searching for articles about "cats" but wants to avoid any mention of "dogs," they could structure their search using “cats NOT dogs.” This targeted approach enhances the precision of the information retrieval process, making it easier to find the intended results.

The other situations presented do not inherently call for the use of Boolean operators. Looking for images or videos related to a topic primarily involves refining the search by media type, which may not require Boolean logic. Additionally, a user wanting to find all articles regardless of content does not need to employ exclusionary tactics like a Boolean search would provide, as it seeks a broad range of results instead of a refined query.
