        "email_analyzer": {
          "tokenizer": "uax_url_email",
          "filter": [
            "lowercase",

          "preserve_original": "true",
          "patterns": [
            "([^@]+)",
            "(\\p{LD}+)",
            "@(.+)",
            "(@)"
          ]
        }
      }
    }
  },
  "mappings" : {
    "properties" : {
