I want to get a doc before update, follow the example.

1º Event  
{"date\_sent":"2018-04-18T13:57:42.005","token":"1"}]

2º Event  
{"date\_open":"2018-04-18T14:57:42.005","token":"1"}]

3º Event  
{"date\_open":"2018-04-18T15:57:42.005","token":"1"}]

I don't want update date\_open from third time, so whenever the end user opens an e-mail, i will write just the first date\_open.

Data on 1º Event

"date\_sent":"2018-04-18T13:57:42.005"  
"token":"1"  
"type":"e-mail"

Data on 2º Event

"date\_sent":"2018-04-18T13:57:42.005"  
"date\_open":"2018-04-18T14:57:42.005"  
"token":"1"  
"type":"e-mail"

Data on 3º Event

"date\_sent":"2018-04-18T13:57:42.005"  
"date\_open":"2018-04-18T14:57:42.005"  
"token":"1"  
"type":"e-mail"

Date\_open must be writen at the first time but never updated !

You should be able to do that with [Scripted Update](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-update.html#_scripted_updates)
