HeinOnline's Venn Diagram Search offers a visual representation of how search terms interact with each other to help users both refine their current search terms and become better researchers going forward.
Searches are constructed by stringing together multiple terms separated by the Boolean operator "AND," with phrases grouped together in quotation marks. For example, let's search for "antitrust enforcement" AND policy AND health AND mandate.
The results displayed on the right side of the page pertain to the search as we originally constructed it (represented by the red slice in the center of the intersecting circles). If we're interested in the results in the other circles, select Clear for the ability to hover over the different segments of the diagram. Once Clear is clicked, the results will vanish from the right side of the page. Now as users hover over the diagram they will see all possible search term combinations from our original query. Click one of these highlighted circles or intersections to explore their results.
Similar to other search results in HeinOnline, you can sort the results for relevance, date, or title. Icons to the right of the results allow you to download a PDF of the section, print, email a PDF link to a friend/colleague, or bookmark the item in your MyHein account.
