Return all results where field is missing or false

I think that you should use "should bool query" Boolean query | Elasticsearch Guide [8.11] | Elastic

Something like this:

POST /index/_search
{
  "query": {
    "bool": {
      "filter": {
        "bool": {
          "should": [
            {
              "term": {
                "myboolean": false
              }
            },
            {
              "bool": {
                "must_not": {
                  "exists": {
                    "field": "myboolean"
                  }
                }
              }
            }
          ]
        }
      }
    }
  }
}

it should just remove all results where myboolean is true

Don't you think you can simplify this with must not term filter myboolean:true?
