Duplicate films or duplicates in the cast/writers/directors array?

Hi, I am doing the optional lab of “Chapter 1: Basic Aggregation - $match and $project” and I dont understand what is asked to.

What do they mean by?

Note that your dataset may have duplicate entries for some films. You do not need to count the duplicate entries.

Is it that there are two or more duplicates of the same film or that the cast, writers, directors array have duplicates?

Hi @Miguel_Escamilla,

Apologies for the confusion here.

This statement means that there can be duplicate entries for the same movie. You can safely ignore this statement in reference to this lab.

Please feel free to reach out if you have any additional questions.

Kind Regards,
Sonali Mamgain
