Anyone tried mongodb.com's Atlas Search?

Yup, this is on Atlas. I confirmed that all the settings on Atlas are correct by setting up a stand-alone node.js app and running the same code using the native node mongo drivers.

So this code works and returns the results as expected:

const MongoClient = require('mongodb').MongoClient;
const uri = <MongoURL>
const client = new MongoClient(uri, { useNewUrlParser: true });
client.connect(async (err) => {
	try {
		const res = await client
			.db('meteor')
			.collection('notifications')
			.aggregate([
				{
					$search: {
						text: {
							query: 'event',
							path: 'title',
						},
					},
				},
			])
			.toArray();
		console.log(res); // Logs a list of search result documents
		console.log(`${res.length} results`);
	} catch (error) {
		console.error(error);
	}
	client.close();
});

I tried to mimic a workaround by using the mongo client within the Meteor server:

import mongodb from 'mongodb';
...
const client = new mongodb.MongoClient(uri, { useNewUrlParser: true }); // Error: <rejected> TypeError: MongoClient is not a constructor

Haven’t figured out what/why that isn’t working because I was under the impression that Meteor ships with the native node mongodb driver. @mullojo and @marklynch got this working though so the fault must be in my Meteor code somewhere.
