It was launched as an early beta version in April 2011. Zanran is based in London, UK. It is the focus on finding graphs, charts, and tables that differentiates Zanran from Google or Bing. A good feature of this search engine is its preview capability. If you hover your mouse over the icons to the left of the results, you get a view of the result's content. This is particularly welcome if the results are in large PDF or Excel files - which you'd otherwise have to download and open.
