Hi all, We have an index of news articles that are tagged with news topics. Currently, we use solr facets to see which topics are popular for a given query or time period. I'd like to apply the concept of IDF to the facet counts so as to penalize the topics that occur broadly through our index. I've begun to write custom facet component that applies the IDF to the facet counts, but I also wanted to check if anyone has experience using facets in this way.
Thanks, Asif
