This demo is an independent service created by Vivisimo to search open source medical content for demonstration purposes only and is not associated with the National Library of Medicine.

Vivisimo's Velocity Search Engine crawled open source medical content including MedlinePlus pages and extracted the most important data from Encyclopedia, Drugs & Supplements and News pages. By searching for health topics like bereavement or back pain, users can access the data from open source medical content without leaving the search results page. In a highlighted area immediately above the search results, users can navigate these high-traffic pages. Additionally, users can hone in on specific questions like what causes chickenpox or what are the symptoms of lupus and get instantaneous answers in the spotlight area. Try other queries like tennis elbow, lyme disease symptoms or paxil side effects to see other examples of Velocity's unique ability to parse and display important data and create virtual documents within the search results page.
