Mongoose/mongodb查找最接近的匹配

const mongoose = require('mongoose');

// 连接MongoDB数据库
mongoose.connect('mongodb://localhost/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true });

// 定义文档模型
const User = mongoose.model('User', {
  name: String,
  age: Number,
  location: String
});

// 查找最接近匹配的文档
User.findOne({ age: { $gte: 18 } }, null, { sort: { age: 1 } }, (err, user) => {
  if (err) {
    console.error(err);
    return;
  }

  console.log(user);
});

// 断开与MongoDB数据库的连接
mongoose.disconnect();
