How do you do your indexing? You would need to have the indexer decide on what the proper category for a document should be, and add that value to the category field. Depending on your requirements, it might be possible to use synonyms in Solr to arrive at something like this. Other than that, Solr has no mechanism to automatically assign a category. You could possibly look at things like Apache Mahout to help you here. Regards, Gora
