In this tutorial, you will learn:

What the $regex operator is and how to use it.

How to find text that contains a specific string (e.g., db.products.find({ name: { $regex: 'phone' } })).

How to find text that starts with a string using the ^ anchor (e.g., db.users.find({ username: { $regex: '^admin' } })).

How to make your search case-insensitive using the $options: 'i' flag.
