Subject Facets with an IDF concept
Date Wed, 17 Jun 2009 10:42:35 GMT
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.
