如何显示elasticsearch JS客户端返回的object中的某些字段？

const { Client } = require('@elastic/elasticsearch');

// 创建elasticsearch客户端
const client = new Client({ node: 'http://localhost:9200' });

// 查询操作
async function search() {
  const { body } = await client.search({
    index: 'my_index',
    body: {
      query: {
        match: { title: 'example' }
      }
    }
  });

  // 获取结果对象中的某些字段
  const hits = body.hits.hits;
  for (const hit of hits) {
    const { field1, field2 } = hit._source; // 替换field1和field2为实际字段名
    console.log(`field1: ${field1}, field2: ${field2}`);
  }
}

// 执行查询操作
search().catch(console.error);
