\Zend_Search_Lucene_Search_Weight_Empty

Package: Zend_Search_Lucene\Search
Calculate query weights and build query scorers.
A Weight is constructed by a query Query->createWeight(). The sumOfSquaredWeights() method is then called on the top-level query to compute the query normalization factor Similarity->queryNorm(float). This factor is then passed to normalize(float). At this point the weighting is complete.
