How to solve this week's survey problem?

Hi team. Does anyone know how to solve this week’s survey quiz?
I tried to use the array finding method, which didn’t work.

How many documents in the results.surveys collection contain a score of 7 for the product, “abc”?

Hi @ran_79956,

Please refer to the Lecture: Array Operators: $elemMatch and you can also go through the following doc to get better understanding of creating the query:

$elemMatch

If you still face any problem, let me know.

Thanks,
Sonali
