mongoose按日期排序，多个查询

const mongoose = require('mongoose');

const postSchema = new mongoose.Schema({
  // 其他字段...
  createdAt: {
    type: Date,
    default: Date.now
  }
});

const Post = mongoose.model('Post', postSchema);

Post.find()
  .sort({ createdAt: -1 }) // 按照日期倒序排序
  .exec((err, posts) => {
    if (err) {
      console.error(err);
      return;
    }
    console.log(posts);
  });

Post.find()
  .or([{ condition1 }, { condition2 }, { condition3 }])
  .sort({ createdAt: -1 })
  .exec((err, posts) => {
    if (err) {
      console.error(err);
      return;
    }
    console.log(posts);
  });
