Abstract Class Zend_Search_Lucene_Search_Weight

Description

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.
