Hello all,

I am using `ES 5.6.3`.  
I save some float array in a field named feature, and I want to use them in script.

My mapping:

```auto
"feature" : {
    "type" : "float",
    "index" : false
},

```

But when I use script like `doc['feature']` to get the data, the order change.  
For example, my raw data is

```auto
[0.3, 0.2, 0.1]

```

Now I get

```auto
[0.1, 0.2, 0.3]

```

I don't want to change the order in the field. I know that I can use `_source` to get the raw data, but it is too slow.

Please give me some help. Thanks in advance!

docvalues are sorted to allowed improved compression. If you want the original order, you either need to use `_source`, or encode the values into a separate field that you can decode in scripting.

Thanks for your response.

However, it is too **slow** to get the raw data using `_source` or saving the in several fields.

Is there any way to prevent es from sorting the docvalues? I heard about that setting `store` to `true` may help, do you have any idea?

Thanks again, may you have a nice day:)
