The Carrot2 web application provides a web front end for visualising the raw results of different index engines. It is based on the open source project "Carrot2", an open source search results clustering engine, capable of automatically organising search results into thematic categories and providing the user with a more intuitive search interface.

In the present setting, it uses the English titles and English abstracts of the returned search results to perform the clustering.

At the moment, the following search engines are available:

  • Solr
  • Terrier
