We have to do aggregations for  
host.os.name, host.name, host.ip

99% data has host.os.name  
95% has host.name  
25% has host.ip

How to ensure I get all the results, even if the field is not present?

So i'm looking for a table like

```auto
| host.os |host.name | host.ip | count|
|---|---|---|--|
|linux | mylinuxhost1 | 172.2.3.4|20|
|linux | mylinuxhost2 | NULL|10|
| windows | winhost1 | 12.2.3.4 |100|
| windows | winhost1 | NULL |5|

```

I was just doing like below, the output gives me ONLY if all the fields are present

```auto
           "aggs": {
             ....
                "group_by_name": {
                    "terms": {
                        "field": "host.name.keyword"
                    },
                    "aggs": {
                      "group_by_ip": {
                          "terms": {
                              "field": "host.ip.keyword"
                          }, ....

```
