In this lesson, we learn that filtering documents from MongoDB collections can be achieved through the find and findOne methods.
We demonstrate how to use these methods to retrieve documents based on specific criteria, such as names or emails, and how to apply regular expressions for more general searches.
Additionally, we explore filtering by array values and using conditions like less than or greater than for numerical properties.
