如何使用2个值编写Mongoose查找过滤器

const mongoose = require('mongoose');
const { Schema } = mongoose;

const userSchema = new Schema({
  name: String,
  age: Number,
  email: String,
});

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

const User = mongoose.model('User', userSchema);

User.find({ age: { $gte: 18 } })
  .then((users) => {
    console.log(users);
  })
  .catch((error) => {
    console.log(error);
  });
