I have a field name across 100 documents. I want to extract the values that the name field has across all documents without returning duplicate.  
how can I achieve that.  
Thanks

ex:  
if the field is called "xyz", aggregate using below payload assuming xyz is string.  
If it's number, then just remove ".keyword".  
"label" is just a name you give for reference when you get the payload back.  
This will give you all unique "xyz" values in your index.

```
{
"aggs": {
    "label": {
      "terms": {
        "field": "xyz.keyword",
        "size": 100
      }
    }
  }
}
```

This is giving me only 10 of the values of the fields.  
so the field is this way,  
"field":{  
"a":,  
"b":  
}

I am trying to get all values of a and b

"size" defaults to 10.
