Hi everybody.

Maybe this is a silly doubt but if someone can answer.

I have 3 docs, 1 with status:true field, 1 with status:false field and 1 doc without status field.

```auto
POST idx_test/_bulk
{"index":{}}
{"name":"xpto 1", "status": true}
{"index":{}}
{"name":"xpto 2", "status": false}
{"index":{}}
{"name":"xpto 3"}

```

I want to use a bool-filter to retrieve all 3 documents. I'm in doubt if I should use match\_all inside the bool-filter or a should. Which of these two would be the best option looking at performance?

Filter with match all:

```auto
GET idx_test/_search
{
  "query": {
    "bool": {
      "filter": [
        {
          "match_all": {
          }
        }
      ]
    }
  }
}

```

Filter + should

```auto
{
  "query": {
    "bool": {
      "filter": [
        {
          "bool": {
            "minimum_should_match": 1,
            "should": [
              {
                "bool": {
                  "must_not": [
                    {
                      "exists": {
                        "field": "status"
                      }
                    }
                  ]
                }
              },
              {
                "term": {
                  "status": {
                    "value": false
                  }
                }
              },
              {
                "term": {
                  "status": {
                    "value": true
                  }
                }
              }
            ]
          }
        }
      ]
    }
  }
}

```
