Watcher alert for matching multiple fields in same index

[Patr123]

Hello, I am trying to match multiple fields in a single index for my watcher alert and having some difficulties doing that.
My watcher looks like:

{
  "trigger": {
    "schedule": {
      "interval": "15m"
    }
  },
  "input": {
    "search": {
      "request": {
        "search_type": "query_then_fetch",
        "indices": [
          "index123"
        ],
        "rest_total_hits_as_int": true,
        "body": {
          "query": {
            "bool": {
              "filter": [
                {
                  "range": {
                    "@timestamp": {
                      "gte": "now-15m",
                      "lte": "now"
                    }
                  }
                }
              ],
              "must": {
                "match": {
                  "LogLevel": "ERROR"
                }
              }
            }
          }
        }
      }
    }
  },
  "condition": {
    "compare": {
      "ctx.payload.hits.total": {
        "gt": 0
      }
    }
  },
  "actions": {
    "log": {
      "logging": {
        "level": "info",
        "text": """{{ctx.payload.hits.total}} Errors have occured in the logs 
:{{#toJson}}ctx.payload.hits.hits{{/toJson}}"""
      }
    },
    "email_administrator": {
      "email": {
        "profile": "standard",
        "attachments": {
          "attached_data": {
            "data": {
              "format": "json"
            }
          }
        },
        "from": "user123@testcompany.com",
        "to": [
          "user456@testcompany.com"
        ],
        "subject": "Test Application encountered  {{ctx.payload.hits.total}} in the last 15 minutes",
        "body": {
          "text": "{{ctx.payload.hits.total}} Errors have occured in the logs "
        }
      }
    }
  },
  "throttle_period_in_millis": 900000
}

The above wathcher is working and sending email as expected.
But now, I also want to match it against one more field called as tags along with the "LogLevel" field and create an alert :

"match": {
                  "tags": "test_env"
                }

and I am having problems in this.

How can I match against multiple fields in the same index and create an alert?

@Patr123 You can add your "tags" field to your bool "must" condition by turning the "must" into an array. e.g.

...
"query": {
    "bool": {
      "must": [
        {
          "match": {
            "LogLevel": "ERROR"
          }
        },
        {
          "match": {
            "tags": "test_env"
          }
        }
      ]
    }
  }
...

You can use the array format for other clauses too.
