Is it possible to have 2 different must not query strings across two different fields

I have this but it doesnt let me have 2 query strings

```auto

GET winevents/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "event.code": {
              "value": "4724"
            }
          }
        }
      ],
      "must_not": [
        {
          "query_string": {
            "query": "*SVC",
            "default_field": "winlog.event_data.SubjectUserName"
          }
        }
      ],
            "must_not": [
        {
          "query_string": {
            "query": "*testcacount",
            "default_field": "winlog.event_data.TargetUserName"
          }
        }
      ],
      "filter": [
        {
          "range": {
            "@timestamp": {
              "from": "now-7d"
            }
          }
        }
      ]
    }
  }
}

```

The `must_not` takes an array so put the two queries in the same must not separated by a comma.

Yes, Give a try...The `must_not` takes an array of queries that must not be matched.

```auto
It doesnt liekit says duplicate query 
GET winevents/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "event.code": {
              "value": "4724"
            }
          }
        }
      ],
      "must_not": [
        {
          "query_string": {
            "query": "*SVC",
            "default_field": "FIELD1",
                        "query": "*testcacount",
            "default_field": "FIELD2"
          }
        }
      ],

      "filter": [
        {
          "range": {
            "@timestamp": {
              "from": "now-7d"
            }
          }
        }
      ]
    }
  }

Hi @Elk_huh

You did not follow my pattern.

Here is a sample working query

```auto
GET logs-*/_search
{
  "query": {
    "bool": {
      "must_not": [
        {
          "term": {
            "kubernetes.namespace": {
              "value": "checkout"
            }
          }
        },
        {
          "term": {
            "kubernetes.namespace": {
              "value": "cart"
            }
          }
        }
      ]
    }
  }
}

```

So yours would look something like this as I showed before 2 separate query\_strings in the Must Not Array

```auto
...
"must_not": [
        {
          "query_string": {
            "query": "*SVC",
            "default_field": "winlog.event_data.SubjectUserName"
          }
        },
        {
          "query_string": {
            "query": "*testcacount",
            "default_field": "winlog.event_data.TargetUserName"
          }
        }
     ]
...

```

BTW Leading `*` queries are very expensive / not efficient

Right ive tried that also , it says duplicate query\_string, TERM1 and Term2 are two different fields  
i understand if it was 1 field  
it would be `"query" : "tesaccount OR *SVC"`  
` " default_field" : "winlog.event_data.TargeUserName"`

This worked fine for me

```auto
GET logs-*/_search
{
  "query": {
    "bool": {
      "must_not": [
        {
          "query_string": {
            "query": "checkout",
            "default_field": "kubernetes.namespace"
          }
        },
        {
          "query_string": {
            "query": "cart",
            "default_field": "kubernetes.namespace"
          }
        }
      ]
    }
  }
}

```

Just substitute your values

Or better yet use term query

```auto
GET logs-*/_search
{
  "query": {
    "bool": {
      "must_not": [
        {
          "term": {
            "winlog.event_data.SubjectUserName": {
              "value": "*SVC"
            }
          }
        },
        {
          "term": {
            "winlog.event_data.TargetUserName": {
              "value": "*testcacount"
            }
          }
        }
      ]
    }
  }
}

```

and again leading `*` is not really good
