You can do that with bool query and combination of must and must_not like this:

GET index/_search
{
    "query": {
        "bool": {
            "must": [
                {"exists": {"field": "field1"}}
            ],
            "must_not": [
                {"term": {"field1": ""}}
            ]
        }
    }
}

I tested this with Elasticsearch 5.6.5 in Kibana.
