Unlock the power of MongoDB queries by combining conditions! This tutorial shows you exactly how to use the logical operators $and, $or, and $not to create complex and precise filters for your data.

What you will learn:

$and (Logical AND): How to find documents that match ALL specified conditions. (Note: This is often implied, but $and is needed for specific structures).

$or (Logical OR): How to find documents that match AT LEAST ONE of the specified conditions.

$not (Logical NOT): How to find documents that DO NOT match a specific condition.

How to combine these operators for powerful, nested queries.

Example Query (Find users who are 25 OR live in "New York"): db.users.find({ $or: [ { age: 25 }, { city: "New York" } ] })

This is essential for any real-world MongoDB application.
