Hello,  
looking for some help to "extract" the first value in an array inside a document.

I have this field called " orchestratorOutput.categoricalListData.ACPredictions " that is logging an array of values (ex.: OTHER, PYMTCONF2, COMPCRI, PYMTCONF, SPAM, OOOAA, R4C\_GENERAL, R4C\_LIFT, R4C\_ABROAD, R4C\_DEATH, R4C\_OUTPORT, INTTEST, R4C\_TOGETHER, R4C\_TELECLUB, R4C\_RETIREMENT, SPONS, R4C\_POST2PRE, R4C\_EMPLLEAVES, R4C\_DATASUB, R4C\_COMPANYCLOSED)

now, I need to return in an new field, just the first value (before the ",")...  
I tried it in several ways, but i'm not able to return it...

f.ex: if I use just doc['orchestratorOutput.categoricalListData.ACPredictions.keyword'].value it returns always "COMPCRI" that is the first value in alphabetical order...  
any tips how to do it?  
thanks a lot.

ps. I'm just a "business"-guy with very limited tech skills 😛

This is a bit difficult to do with Elasticsearch as all arrays that are indexed in Elasticsearch won't be ordered, they will be like a bag of elements. The simplest way would be to either get the first element at ingest or to save the field as a string(again, at ingest, before it was indexed).  
Otherwise, you would have to enable the `_source` field and then use something like:  
`params._source['orchestratorOutput.categoricalListData.ACPredictions']` in order to access the ordered array.

Hello @Marius_Dragomir, thanks a lot for your support!  
luckily \_source field is already enabled...

I tried with your suggested code and I always get " - " as result.

then I tried just params.\_source.orchestratorOutput.categoricalListData.ACPredictions and it returns the full content.  
what I would need is just the first word before the first " , "

thanks again and have a nice day 🙂  
cheers  
Hugo

You can some java functions for this:

```auto
text = params._source.orchestratorOutput.categoricalListData.ACPredictions;
first_comma = text.indexof(',');
if (first_comma != -1) {
return "Empty"
} else {
return text.substring(0, first_comma)
}
```
