如何在创建索引时向索引添加设置和映射

如何解决如何在创建索引时向索引添加设置和映射

我想索引一个包含世界城市名称的 .json 文件。 我在创建索引时有我的自定义设置和映射。 我的代码是：

const elasticsearchLoading = require("elasticsearch");
const indexNameLoading = "cities";
const dataJsonFile = "./cities.json";

const loadindexclient = new elasticsearchLoading.Client({
    hosts: ["http://localhost:9200"],});

// create a new index
loadindexclient.indices.create({
    index: indexNameLoading,},function (error,response,status) {
    if (error) {
        console.log(error);
    }
    else {
        console.log("created a new index",response);
    }
});
// add 1 data to the index that has already been created
loadindexclient.index({
    index: indexNameLoading,type: "cities_list",body: {
        name: "Content for key one"
    },status) {
    console.log(response);
});
// require the array of cities that was downloaded
const cities = require(dataJsonFile);
// declare an empty array called bulk
let bulk = [];

cities.forEach((city) => {
    bulk.push({
        index: {
            _index: indexNameLoading,_type: "cities_list",});
    bulk.push(city);
});
//perform bulk indexing of the data passed
loadindexclient.bulk({ body: bulk },function (err,response) {
    if (err) {
        // @ts-ignore
        console.log("Failed Bulk operation".red,err);
    }
    else {
        // @ts-ignore
        console.log("Successfully imported ",cities.length);
    }
});

当我运行此代码时，它实际上会运行并创建索引，但默认情况下会创建映射和设置。但我希望在创建索引时添加以下设置和映射。

"settings": {
    "analysis": {
      "filter": {
        "my_ascii_folding": {
          "type": "asciifolding","preserve_original": true
        }
      },"analyzer": {
        "turkish_analyzer": {
          "tokenizer": "standard","filter": [
            "lowercase","my_ascii_folding"
          ]
        }
      }
    }
  },"mappings": {
    "test": {
      "properties": {
        "name": {
          "type": "string","analyzer": "turkish_analyzer"
        }
      }
    }
  }

可以吗？

解决方法

当然，您可以将配置作为 index.create body 参数传递。

文档：https://www.elastic.co/guide/en/elasticsearch/client/javascript-api/current/api-reference.html#_indices_create

// create a new index
loadIndexclient.indices.create({
    index: indexNameLoading,body: {
        "settings": {
            "analysis": {
            "filter": {
                "my_ascii_folding": {
                "type": "asciifolding","preserve_original": true
                }
            },"analyzer": {
                "turkish_analyzer": {
                "tokenizer": "standard","filter": [
                    "lowercase","my_ascii_folding"
                ]
                }
            }
            }
        },"mappings": {
            "properties": {
                "name": {
                "type": "string","analyzer": "turkish_analyzer"
                }
            }
        }
        }
},function (error,response,status) {
    if (error) {
        console.log(error);
    }
    else {
        console.log("created a new index",response);
    }
});

执行此操作的理想方法是使用 index_templates。请参阅文档 here
