Hi,  
I have a index mappings like this:

```auto
...
"location": {
          "type": "nested",
          "properties": {
            "accuracy": {
              "type": "float"
            },
            "lat": {
              "type": "float"
            },
            "lon": {
              "type": "float"
            }
          }
        },
...

```

I would create an ingestion pipeline that creates a new field (for example "geo") only with lat and lon subfield, without accuracy.

How can I do?  
Thanks

And whats your issue?  
Just use the set processor

I dont know how to do.

I have to use "copy\_from"? How can I copy only two fields of location?
