getValues(LeafReaderContext ctx,

Returns a
DoubleValues instance for the passed-in LeafReaderContext and scores
If scores are not needed to calculate the values (ie returns false , callers
may safely pass null for the scores parameter. |

Return true if document scores are needed to calculate values

rewrite(IndexSearcher searcher)
Return a DoubleValuesSource specialised for the given IndexSearcher
Implementations should assume that this will only be called once.

Queries that use DoubleValuesSource objects should call rewrite() during
Query.createWeight(IndexSearcher, ScoreMode, float)
rather than during
Query.rewrite(IndexReader)
to avoid IndexReader reference leakage.
For the same reason, implementations that cache references to the IndexSearcher
should return a new object from this method.rewrite
