      • FeatureWeight

        public FeatureWeight​(org.apache.lucene.search.Query q,
                             org.apache.lucene.search.IndexSearcher searcher,
                             SolrQueryRequest request,
                             org.apache.lucene.search.Query originalQuery,
                             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().
        Parameters:
        q - Solr query associated with this FeatureWeight
        searcher - Solr searcher available for features if they need them

      • toString

        public String toString()
        Used in the FeatureWeight's explain. Each feature should implement this returning properties of the specific scorer useful for an explain. For example "MyCustomClassFeature [name=" + name + "myVariable:" + myVariable + "]"; If not provided, a default implementation will return basic feature properties, which might not include query time specific values.
        Overrides:
