Snažím se vytvořit vlastní analyzátor v elasticsearch. zde je analyzátor

{
  "settings": {
    "analysis": {
      "analyzer": {
        "my_analyzer": {
          "tokenizer" : "standard",
          "filter" : ["custom_stopper", "custom_stems", "custom_synonyms"]
        },
        "filter" : {
            "custom_stopper" : {
                "type" : "stop",
                "stopwords_path" : "analyze/stopwords.txt"
            },
            "custom_stems" : {
                "type" : "stemmer_override",
                "rules_path" : "analyze/stem.txt"
            },
            "custom_synonyms" : {
                "type" : "synonyms",
                "synonyms_path" : "analyze/synonym.txt"

            }
        }
        }
      }
    }
  }

                "type": "illegal_argument_exception",
                "reason": "analyzer [filter] must specify either an analyzer type, or a tokenizer"
            }
        ],
        "type": "illegal_argument_exception",
