Elasticsearch 同义词错误 - mapper_parsing_exception

Question

I'm trying to run the code below but I'm getting this error. Please help me fix it. Thanks:

PUT synonyms_hotel
{
  "settings": {
    "index": {
      "analysis": {
        "analyzer": {
          "synonym_analyzer": {
            "tokenizer": "standard",
            "filter": [
              "lowercase",
              "synonym_graph"
            ]
          }
        },
        "filter": {
          "synonym_graph": {
            "type": "synonym_graph",
            "synonyms": [
              "courtyard, marriot"
            ]
          }
        }
      }
    }
  },
  "mappings": {
    "hotel": {
      "properties": {
        "name": {
          "type": "text",
          "fields": {
            "raw": {
              "type": "keyword"
            }
          }
        },
        "city": {
          "type": "text",
          "fields": {
            "raw": {
              "type": "keyword"
            }
          }
        },
        "name_suggest": {

          "analyzer": "autocomplete",
          "search_analyzer": "standard"
        }
      }
    }
  }
}

You're probably using Elasticsearch 7+ and the mapping types have been deprecated , so you simply need to remove the hotel level:

PUT synonyms_hotel
{
  "settings": {
    "index": {
      "analysis": {
        "analyzer": {
          "synonym_analyzer": {
            "tokenizer": "standard",
            "filter": [
              "lowercase",
              "synonym_graph"
            ]
          }
        },
        "filter": {
          "synonym_graph": {
            "type": "synonym_graph",
            "synonyms": [
              "courtyard, marriot"
            ]
          }
        }
      }
    }
  },
  "mappings": {
      "properties": {                     <--- remove hotel here
        "name": {
          "type": "text",
          "fields": {
            "raw": {
              "type": "keyword"
            }
          }
        },
        "city": {
          "type": "text",
          "fields": {
            "raw": {
              "type": "keyword"
            }
          }
        },
        "name_suggest": {
          "type": "completion",
          "analyzer": "autocomplete",
          "search_analyzer": "standard"
        }
      }
    }
}
