| BoostingQuery | 
 The BoostingQuery class can be used to effectively demote results that match a given query. 
 | 
| CommonTermsQuery | 
 A query that executes high-frequency terms in a optional sub-query to prevent
 slow queries due to "common" terms like stopwords. 
 | 
| CustomScoreProvider | 
 An instance of this subclass should be returned by
  
CustomScoreQuery.getCustomScoreProvider(org.apache.lucene.index.LeafReaderContext), if you want
 to modify the custom score calculation of a CustomScoreQuery. | 
| CustomScoreQuery | 
 Query that sets document score as a programmatic function of several (sub) scores:
 
    the score of its subQuery (any query)
    (optional) the score of its  
FunctionQuery (or queries).
 
 Subclasses can modify the computation by overriding CustomScoreQuery.getCustomScoreProvider(org.apache.lucene.index.LeafReaderContext). |
