      • FeatureWeight

        public FeatureWeight(Query q,
                             IndexSearcher searcher,
                             SolrQueryRequest request,

                             Map<String,String[]> efi)
        Initialize a feature without the normalizer from the feature file. This is called on initial construction since multiple models share the same features, but have different normalizers. A concrete model's feature is copied through featForNewModel().
        q - Solr query associated with this FeatureWeight
        searcher - Solr searcher available for features if they need them
