If I run the following query:

    "query": {
        "bool": {
            "must": [
                {

                    }
                }
            ],

                        }
                    }
                }
            ],
            "filter": [

I get the following validation error from elasticsearch:

{
    "ok": false,
    "errors": {
        "validation": [
            {
                "message": "\"query.bool.must_not\" is not allowed",

                                        "mx"
                                    ],
                                    "minimum_should_match_script": {

                                    }
                                }
                            }
                        }
                    ],
                    "key": "must_not"
                }
            }
        ]
    },
    "correlationId": "d29e9275-9ab3-4ff8-944d-852b98d4b503"
}

And I cannot figure out what the issue might be! From the elastic docs it should be OK.

I'm using ElasticSearch 7.9.3 running in a local docker container.

I'm hoping someone out there will give me a clue!

Cheers!

I would expect this to just work.

I'm trying to filter out articles that have both of the country codes gb and mx in the field allowedCountries.

I can include them easily enough in the results when I add the terms_set query to the bool.must section of the query.

CodePudding user response：

It works well, you just need to enclose your query in the query section

{
    "query": {        <--- add this 
       "bool": {      <--- your query starts here
          "must": [
      ...

CodePudding user response：

Thank you for responding!

I was helping with a system I did not have full context on - it turns out there is a proxy in the mix with validation that was blocking the must_not query. So, with the proxy fixed, it now works.
