Elasticsearch Node.js客户端:从对象中删除嵌套元素

const { Client } = require('@elastic/elasticsearch');
const client = new Client({ node: 'http://localhost:9200' });

const removeNestedElement = async (index, id, nestedFieldName) => {
  await client.update({
    index: index,
    id: id,
    body: {
      script: {
        lang: 'painless',
        source: `ctx._source.remove('${nestedFieldName}')`
      }
    }
  });
}

// 调用方法删除嵌套元素
removeNestedElement('my_index', '1', 'nested_field');

const { Client } = require('@elastic/elasticsearch');
const client = new Client({ node: 'http://localhost:9200' });

const deleteDocumentsByQuery = async (index, query) => {
  await client.deleteByQuery({
    index: index,
    body: {
      query: query
    }
  });
}

// 构建删除嵌套元素的查询条件
const query = {
  match: {
    'nested_field.field_name': 'value'
  }
};

// 调用方法删除符合条件的文档
deleteDocumentsByQuery('my_index', query);
