Examples of DoubleDocValuesField

org.apache.lucene.document.DoubleDocValuesField
Syntactic sugar for encoding doubles as NumericDocValues via {@link Double#doubleToRawLongBits(double)}.
Per-document double values can be retrieved via {@link FieldCache#getDoubles(AtomicReader,String,boolean)}.
NOTE: In most all cases this will be rather inefficient, requiring eight bytes per document. Consider encoding double values yourself with only as much precision as you require.
