Master MongoDB's most important comparison operators! This tutorial shows you exactly how to use $gt (greater than), $lt (less than), $gte (greater than or equal to), and $lte (less than or equal to) to find the exact data you need.

Learn how to filter your documents by number, date, or even string values. We'll show you practical examples for each operator.

What you will learn:

$gt (Greater Than): How to find documents where a value is more than a number (e.g., find all products with a price greater than 50).

$lt (Less Than): How to find documents where a value is less than a number (e.g., find all users with an age less than 30).

$gte (Greater Than or Equal To): How to find documents including the number (e.g., find all employees with experience greater than or = 5 years).

$lte (Less Than or Equal To): How to find documents including the number (e.g., find all items with stock Less than or = 10).

Combining Operators: How to create powerful range queries (e.g., find all sales between $10 and $20).

Example Query (Find items with a price between 20 and 50): db.products.find({ "price": { $gt: 20, $lt: 50 } })
