I am using Elasticsearch 6.5.  
Let say, that my Elasticsearch document looks like this:

```auto
"_source" : {
    "field1" : "val1",
    "field2" : "val2",
    "struct1" : {
      "inner_field1" : "inner val1",
      "inner_field2" : "inner val2",
    }
  }

```

I would like to delete one of inner fields in this structure.  
I tried following code:

```auto
POST test_idx1/_doc/1/_update
{
 "script": "ctx._source.remove('struct1.inner_field1');"
}

```

and the result says `updated`, but nothing changes.  
How to perform such action?

Ok, solved it with following syntax:

```auto
POST test_idx1/_doc/1/_update
{
 "script": "ctx._source.struct1.remove('inner_field1');"
}

```
