Help needed scripting update to list element (bulk request)

Elastic Stack Elasticsearch
1

Hi
Say I have a list of elements like this:

PUT twitter/twit/1
{
"list": [
{
"a": "b",
"c": "d",

  •          "e": "f"*
      },
      {
        "1": "2",
        "3": "4"
      }
  ]

}

And I want to change the value of "e" (currently "f") to say "new_f " such
that the document looks like:

{
"list": [
{
"a": "b",
"c": "d",

  •          "e": "new_f"*
      },
      {
        "1": "2",
        "3": "4"
      }
  ]

}

Is there a way to do this ? Maybe in MVEL ?

Do I match on document
{
"a": "b",
"c": "d",
"e": "f"
}

ie if list.contains(document) { some kind of update; } // is this possible
?

I know MVEL is being deprecated in 1.4 however it will do for now.

I want to use bulk request.

I know it's possible to remove the element like this:
bulkRequestBuilder.setScript("if (ctx._source.list.contains(document))
{ctx._source.list.remove(document)} }").setScriptParams etc

but is it possible to "update" a field in the document also ?

Thanks.

Hey

I figured it out, but it leads me on to another question.

So the way to execute a script over a list of elements is as follows:

PUT twitter/twit/1
{
"list": [
{
"tweet_id": "1",
"a": "b"
},
{
"tweet_id": "123",
"a": "f"
}
]
}

POST /twitter/twit/1/_update
{
"script": "foreach (item : ctx._source.list) {if (item['tweet_id'] ==
tweet_id) { item['new_field'] = 'ghi'; } }",
"params": {
"tweet_id": "123"
}
}

My next question: how can I query the index to find all matching documents
with say "tweet_id": "123" and then execute the script on only those
documents?

When I tried
.. query..
{
"filter": {
"script": "foreach (item : ctx._source.list) {if (item['tweet_id'] ==
tweet_id) { item['new_field'] = 'ghi'; } }",
"params": {
"tweet_id": "123"
}
}
}
I got an error saying property : ctx : unresolvable

Thanks.

You can't do it with elasticsearch but you could try this plugin: GitHub - yakaz/elasticsearch-action-updatebyquery: ElasticSearch Update By Query action plugin
