Elastic match_bool_prefix and must

Question

According to docs https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-match-bool-prefix-query.html match_bool_prefix is equivalent to

{
  "query": {
    "bool" : {
      "should": [
        { "term": { "message": "quick" }},
        { "term": { "message": "brown" }},
        { "prefix": { "message": "f"}}
      ]
    }
  }
}

Is there an equivalent query that is equivalent to

{
  "query": {
    "bool" : {
      "must": [
        { "term": { "message": "quick" }},
        { "term": { "message": "brown" }},
        { "prefix": { "message": "f"}}
      ]
    }
  }
}

Edit based on comment:

You can impose an AND condition on the match_bool_prefix query by setting the operator parameter as follows:

{
  "query": {
    "match_bool_prefix": {
      "message": {
        "query": "quick brown f",
        "operator": "and"
      }
    }
  }
}

Note that this is not exactly equivalent to the bool > must query in your example, because that query requires an exact match (term query) of two different values for the same field (message, in your case).
