如何使用定義的分析器和分片在 Elasticsearch 中創建索引？

Question

我正在嘗試使用定義了分析器的文本和關鍵字的映射來創建索引，這是我迄今為止所嘗試的：

{
    "settings" : {
        "number_of_shards" : 2,
        "number_of_replicas" : 1
    },

    "analysis": {
      "normalizer": {
        "my_normalizer": {
          "type": "custom",
          "char_filter": [],
          "filter": ["lowercase", "asciifolding"]
        }
      }
    }
  ,
    "mappings": {
    "properties": {
  "question": {
    "type":"text",
    "fields": {
      "keyword": {
        "type": "keyword"
      },
     "normalize": {
      "type": "keyword",
      "normalizer": "my_normalizer"
    }

}
}
}
}
}

我試過這個但得到錯誤：

"error": {
    "root_cause": [
        {
            "type": "parse_exception",
            "reason": "unknown key [analysis] for create index"
        }
    ],
    "type": "parse_exception",
    "reason": "unknown key [analysis] for create index"
},
"status": 400

}

問題是我需要添加此映射的字段。 我正在 AWS ES 服務中嘗試這個。

很好的開始，你就快到了！

analysis部分需要位於頂級settings部分內，如下所示：

{
  "settings": {
    "index": {
      "number_of_shards": 2,
      "number_of_replicas": 1
    },
    "analysis": {
      "normalizer": {
        "my_normalizer": {
          "type": "custom",
          "char_filter": [],
          "filter": [
            "lowercase",
            "asciifolding"
          ]
        }
      }
    }
  },
  "mappings": {
    "properties": {
      "question": {
        "type": "text",
        "fields": {
          "keyword": {
            "type": "keyword"
          },
          "normalize": {
            "type": "keyword",
            "normalizer": "my_normalizer"
          }
        }
      },
      "answer": {
        "type": "text",
        "fields": {
          "keyword": {
            "type": "keyword"
          },
          "normalize": {
            "type": "keyword",
            "normalizer": "my_normalizer"
          }
        }
      }
    }
  }
}
