    "bool": {
      "should": [
        {
          "match_phrase": {
            "message": "AC949111"
          }
        },
        {
          "match_phrase": {
            "message": "AC949110"
          }
        },

// Here I need to add/create a field (references) and fill it with the same value I found above in the message (AC949111/AC949110/....)
        }
      ],
