Elastic Query string not equal to

We have some requirement in kibana where we need to exclude some request urls like ‘/ibe/document/*’ and fetch the other requests.

Options Tried

We have tried the below options

1. { "query": { "bool" : { "must_not" : { "term" : { "request.keyword" : "/ibe/document/.*" } } } } }
2. NOT ( "request.keyword" : "/ibe/document/.*")
3. !("request.keyword" : "/ibe/document/.*")

But even if we use any of the above queries, In the filtered data, we are still getting records with "request.keyword" : "/ibe/document/”. Can you provide suggestions on query to avoid this "request.keyword" : "/ibe/document/."

I have tried running all the above with "request.keyword" : "/ibe/document/." and "request.keyword" : "/ibe/document/" . But every time, the records corresponding to requests "request.keyword" : "/ibe/document/*" are being fetched

You can use the below wildcard query to exclude all the results that start from /ibe/document/

{
  "query": {
    "bool": {
      "must_not": {
        "wildcard": {
          "request.keyword": "/ibe/document/*"
        }
      }
    }
  }
}
