> Cause of SOLR-13315
> Index-specific DoubleValuesSources can be created by 
> DoubleValuesSource.rewrite(), and the various consumers of these sources are 
> careful not to store these rewritten sources on long-lived objects, such as 
> queries that may be re-used between searchers.  However, the bridge code 
> between ValueSource and DoubleValuesSource does not return a new object from 
> its rewrite method, instead caching the passed-in IndexSearcher, which means 
> references to this searcher may leak.
