Yippy is a metasearch engine that groups search results into clusters.
It automatically categorizes search results by content, and organizes by topics, sites, time, and sources, which users can use to narrow results. Clicking on a topic changes the results to only show those from that topic. Click the plus sign next to a topic to see other topics to further narrow a search.
If you’re searching a broad concept, Yippy is a good alternative to Google or Bing.
