hi all !  
i'm trying to filter data with Lucene. I wish filtered the data having 2 fields exists.  
I tried with this code but it doesn't work :

```auto
{
  "query": {
    "bool" : {
		"must": {
			"exists": {
				"field": "total",
				"field": "machine"
			}
		}
    }
  }
}

```

Is it possible to do this ?  
Thanks.

I think this should be something like:

```auto
{
  "query": {
    "bool" : {
		"must": [{
			"exists": {
				"field": "total"
			}
		},{
			"exists": {
				"field": "machine"
			}
		}]
    }
  }
}

```

Thank you David,  
In fact, this generate an AND request. I want simply an OR type request 🙂
