使用示例

本节中的示例基于以下 Elastic 实例

version: '3.5'
services:
  elastic:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.10.0
    ports:
      - 9200:9200
      - 9300:9300
    environment:
      - discovery.type=single-node

该实例的数据集通过下载此文件并执行命令创建

curl -H 'Content-Type: application/json' -XPOST 'localhost:9200/bank/_bulk?pretty&refresh' --data-binary '@accounts.json'

我们可以通过运行以下查询来查找 id 为 1 的文档

CALL apoc.es.get("localhost","bank","_doc","1",null,null);

表 1. 结果
值
{_seq_no: 0, found: TRUE, _index: "bank", _type: "_doc", _source: {account_number: 1, firstname: "Amber", address: "880 Holmes Lane", balance: 39225, gender: "M", city: "Brogan", employer: "Pyrami", state: "IL", age: 32, email: "amberduke@pyrami.com", lastname: "Duke"}, _id: "1", _version: 1, _primary_term: 1}
