Aggs with painless script on an object containing an array

[TeePee]

Hi guys,

I'm using ES 5.0 and how can I represent an object containing an array using painless script, since doc.extra_data.nID_deals.value doesn't seem to do the job?

Take a look:
"inline":"doc.deal_id.value == params.nDealID ? doc.deal_id.value : doc.extra_data.nID_deals.value"

curl -XPOST "http://localhost:9200/tracking-*/_search/?pretty=true&request_cache=true" -d'
{  
  "_source":[  
     "timestamp_ocurred",
     "action",
     "campaign_id",
     "esp_id",
     "user_id",
     "geo",
     "extra_data.nID_deals",
     "deal_id"
  ],
  "query":{  
     "multi_match":{  
        "query":465,
        "fields":[  
           "deal_id",
           "extra_data.nID_deals"
        ]
     }
  },
  "size":0,
  "aggs":{  
     "DEAL":{  
        "terms":{  
           "script":{  
              "lang":"painless",
              "inline":"doc.deal_id.value == params.nDealID ? doc.deal_id.value : doc.extra_data.nID_deals.value",
              "params":{
                "nDealID":465
              }
           }
        }
...

TIA

That should work, unless one of the intermediate objects is mapped as nested. Is it the case?

It should @jpountz

It looks like at least one of the queried indices does not have a mapping for the deal_id field.
