Support MongoDB Atlas full text search

[sanderfish]

Feature request

MongoDB Atlas announced Atlas Search is now generally available:

https://www.mongodb.com/atlas/search
https://docs.atlas.mongodb.com/atlas-search/

Mongoose (5.9.17) currently doesn't support the Atlas Search $search pipeline in aggregations. It throws the error

MongoError: Unrecognized pipeline stage name: '$search'

It would be amazing if Mongoose could support Atlas Search.

That error comes from MongoDB, not Mongoose. Make sure you're connecting to MongoDB Atlas and your cluster is running at MongoDB 4.2 or higher: https://docs.atlas.mongodb.com/atlas-search/. Below script works fine against my Atlas cluster:

'use strict';
  
const mongoose = require('mongoose');

mongoose.set('useFindAndModify', false);

const { Schema } = mongoose;

run().catch(err => console.log(err));

async function run() {
  await mongoose.connect('mongodb+srv://OMITTED:OMITTED@OMITTED.mongodb.net/sample_mflix?retryWrites=true&w=majority', {
    useNewUrlParser: true,
    useUnifiedTopology: true
  });

  const Movie = mongoose.model('Movie', Schema({
    title: String,
    plot: String
  }));

  const res = await Movie.aggregate([
  {
    $search: {
      "text": {
        "query": "baseball",
        "path": "plot"
      }
    }
  },
  {
    $limit: 5
  },
  {
    $project: {
      "_id": 0,
      "title": 1,
      "plot": 1
    }
  }
  ]);

  console.log('Result', res);
}

That being said, we'll add a Aggregate#search() helper for consistency with other pipeline stages.
