The following two queries gives me different results when some documents has missing fields:  
Query1, SELECT \* FROM table WHERE colE \<= 9 OR colD \>= 6

```
{
  "query": {
    "bool": {
      "should": [
        {
          "range": {
            "colE": {
              "lte": "9"
            }
          }
        },
        {
          "range": {
            "colD": {
              "gte": "6"
            }
          }
        }
      ]
    }
  }
}

```

Query2, SELECT \* FROM table WHERE NOT (colE \> 9 AND colD \< 6)

```
{
    "query": {
    "bool": {
      "must_not": [
        {
          "bool": {
            "filter": [
              {
                "range": {
                  "colE": {
                    "gt": "9"
                  }
                }
              },
              {
                "range": {
                  "colD": {
                    "lt": "6"
                  }
                }
              }
            ]
          }
        }
      ]
    }
  }
}

```

The difference is that the 2nd query will return one more document that does not have colD and w/ colE = 14. Can anyone provide some hints on the difference between these 2 queries (especially on how they deal with missing fields)? Thank you so much!
