\Zend_Search_Lucene_Search_Weight_MultiTerm
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.
