What is the syntax of kibana filter mismatch?

I want to drop the url field in kibana visualize, Filter, which ends with js. How do I write query dsl?? I can"t write it in the following way

{
  "query": {
    "bool": {
      "must_not": [
        {
          "match": "js"
        }
      ]
    }
  }
}
