I'm doing an index action in my watch's Actions block for docs from a \_doc payload (see code below). Index action works fine, however, I have duplicate docs and haven't figured out how to evaluate the "doc\_id" value in a dynamic way within my index action given a "\_doc" payload source:

```
"actions" : {
  "index_matches" : {
	"transform" : {
		"chain": [
		{ 
			"search" : {
				"request" : {
					"indices" : "rq-snow",
				    "body" : {
				      "size": 1000000,
						  "query" : { 
							  "match" : { 
								  "ip": "{{#ctx.payload.hits.hits}} {{_source.ip}} {{/ctx.payload.hits.hits}}"
							  }
						  }
					  }
			    }
		    }
		},	
		{
			"script": {
				"inline": "def document = []; for(item in ctx.payload.hits.hits) {document.add(item._source);} return [\"_doc\" : document];"
			}
		}
		]		
    },
	"index" : {
		"index" : "rq-snow-aware", 
		"doc_type" : "Hit",
		}
	}
}
```

Hey,

you need a `_doc` array in the following structure to index by id.

```auto
_doc = [
 { "_id" : 1234, "foo":"bar", "spam": "eggs" }
]

```

This means you need to extract the metadata from the hit and add the id field as part of the second transform.

Hope this helps.
