How to add multiple exists fields with OR operation in elasticsearch

Question

I have the following query:

{
  "query": {
    "exists": {
      "field": "field1"
    }
  }
}

I would like my query to be modified in a way that I could add another filter with existing field having 'OR' operation between them.

Any idea how to do so?

Thanks.

You can use Bool Query with should.

{
    "query": {
        "bool": {
            "should": [{
                "exists": {
                    "field": "field1"
                }
            },
            {
                "exists": {
                    "field": "field2"
                }
            }
            ]
        }
    }
}
