            "bool": {
              "must": [
                {
                  "match_data": {
                    "Event.Data.message": "#(Paramtervale)"
                  }
                },
                {
                  "match_data": {
                    "Event.Name": "#(Paramtervale2)"
                  }
                }
              ],
              "filter": {
                "range": {
                  "@timestamp": {
                    "gte": "now-1m"
                  }
                }
              }
            }
          }
        }
            """
* set request.Event.Data.message = myvalue

Here are 2 different ways, note that for updating a JSON, set is not needed any more. When special characters are in key names, use the square-bracket approach to refer to JSON data:

* def temp = { 'a.b': 'xxx' }
* temp['a.b'] = 'yyy'
* match temp == { 'a.b': 'yyy' }

# using embedded expressions
* def val = 'yyy'
* def temp = { 'a.b': '#(val)' }
* match temp == { 'a.b': 'yyy' }
