GetDoubles(AtomicReader, String, FieldCache.IDoubleParser, Boolean)

Returns a FieldCache.Doubles over the values found in documents in the given field. If the field was indexed as NumericDocValuesField, it simply uses GetNumericDocValues(String) to read the values. Otherwise, it checks the internal cache for an appropriate entry, and if none is found, reads the terms in field as s and returns an array of size reader.MaxDoc of the value each document has in the given field.
