Hi guys, I know that for execute a "exists" query in a nested type I could use a nested query.  
But how about simple Object type?

I am doing this:

{  
"from" : 0,  
"size" : 10,  
"query" : {  
"bool" : {  
"must" : [  
{  
"match\_all" : {  
}  
},  
{  
"exists" : { "field" : "object\_type\_field" }  
}  
]  
}  
}  
}

Hi,  
Would a must match work? See here: [https://www.elastic.co/guide/en/elasticsearch/guide/master/nested-query.html](https://www.elastic.co/guide/en/elasticsearch/guide/master/nested-query.html)

No, because the field is not a nested type ☹

"caused\_by": {  
"type": "illegal\_state\_exception",  
"reason": "[nested] nested object under path [item\_availability\_hours] is not of nested type"  
}

here is the field:

```
{
    "properties": {
      "item_availability_hours": {
        "properties": {
          "FRIDAY": {
            "type": "nested",
            "properties": {
              "end": {

              },
              "start": {

            }
