This widget displays topics that are related to the current search. Larger topics indicate that a significant amount of the search results are related to that topic. You can click any of the related topics to add that topic to your search. You can remove a topic by clicking the x next to it in the title bar of the search results. Any time that you change your search, by adding a refinement, related topic, or changing the query, a new list of related topics will be generated.
