One of the main features of Solr is Faceted Search. Facets are the top terms present in the results of a query. But facets do not indicate the most statistically relevant terms of a query, that is, these terms that are more present in the documents selected by the query than in the rest of the collection. A critical factor in making such statistical insights broadly useful is to make them visual -- i.e., using charts and graphs that display these quantitative relationships. We will present how to adapt Ajax-Solr to find the most prominent terms of a query compared to the full set or just another query. We are going to present and example on how this can be used to find current topics in the news, and extract that information into visually communicative charts and graphs.
