Why ScriptDocValues.Doubles is sorted ?

[HorsonLiu]

mappping:
{ "settings" : { "index" : { "number_of_shards" : 1, "number_of_replicas" : 0 } }, "mappings": { "obj_type": { "properties": { "feature_value": { "type": "double" }, } } } }

doc:
{"feature_value":[0.5, 0.1, 0.3]}

In self-defined SearchScript, I use ((ScriptDocValues<List>) getDoc().get(field)).get(0) returns 0.1 , but not 0.5. Why ? How can I retrieve the original double array, e.g. [0.5, 0.1, 0.3], not [0.1, 0.3, 0.5] ?
Thanks !

Multivalued docvalues are stored as sorted at the lucene level, so lose their original ordering when indexed. If you need to preserve the ordering, you could try encoding the values in a binary field and retrieving them from BinaryDocValues at search time, or storing them as separate fields.

Thank you !
With cmd curl -XGET http://<ip>:<port>/<index>/<type>/<ID> I got the 'feature_value' in original order. So I don't think docvalues stored as sorted at the lucene level.
