Zend_Search_Lucene_Search_Weight
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.

float
$_queryNorm
(line 47)
Normalization factor.
This value is stored only for query expanation purpose and not used in any other place
float
$_value
(line 58)
Weight value
Weight value may be initialized in sumOfSquaredWeights() or normalize() because they both are invoked either in Query::_initWeight (for top-level query) or in corresponding methods of parent query's weights
getValue (line 66)
The weight for this query.
- Zend_Search_Lucene_Search_Weight_MultiTerm::getValue() : The weight for this query Standard Weight::$_value is not used for boolean queries
- Zend_Search_Lucene_Search_Weight_Boolean::getValue() : The weight for this query Standard Weight::$_value is not used for boolean queries
normalize (line 83)
Assigns the query normalization factor to this.
- $norm $norm
- Zend_Search_Lucene_Search_Weight_MultiTerm::normalize() : Assigns the query normalization factor to this.
- Zend_Search_Lucene_Search_Weight_Boolean::normalize() : Assigns the query normalization factor to this.
- Zend_Search_Lucene_Search_Weight_Phrase::normalize() : Assigns the query normalization factor to this.
- Zend_Search_Lucene_Search_Weight_Term::normalize() : Assigns the query normalization factor to this.
- Zend_Search_Lucene_Search_Weight_Empty::normalize() : Assigns the query normalization factor to this.
sumOfSquaredWeights (line 76)
The sum of squared weights of contained query clauses.
- Zend_Search_Lucene_Search_Weight_MultiTerm::sumOfSquaredWeights() : The sum of squared weights of contained query clauses.
- Zend_Search_Lucene_Search_Weight_Boolean::sumOfSquaredWeights() : The sum of squared weights of contained query clauses.
- Zend_Search_Lucene_Search_Weight_Phrase::sumOfSquaredWeights() : The sum of squared weights of contained query clauses.
- Zend_Search_Lucene_Search_Weight_Term::sumOfSquaredWeights() : The sum of squared weights of contained query clauses.
- Zend_Search_Lucene_Search_Weight_Empty::sumOfSquaredWeights() : The sum of squared weights of contained query clauses.
