从mongodb文档的两个属性中查找单词

// 连接到mongodb数据库
const MongoClient = require('mongodb').MongoClient;
const uri = 'mongodb://localhost:27017';
const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });
client.connect(async (err) => {
  if (err) throw err;
  
  // 选择目标集合
  const db = client.db('mydb');
  const collection = db.collection('mycollection');
  
  // 构建查询条件
  const query = {
    $or: [
      { attribute1: 'targetWord' },
      { attribute2: 'targetWord' }
    ]
  };
  
  // 执行查询
  const result = await collection.find(query).toArray();
  
  // 获取结果
  console.log(result);
  
  // 关闭数据库连接
  client.close();
});
