How do I slice a nested array and how do I update a specific field in it?

Hi @Ajay_Pillay . The next is the more close I got until now:

I insert more fields:

db.product.find({ “_id”:“some_id”},{ “array1.array2.count”:1} ).pretty()

I am testing some MQL expressions using logics, comparatives and projections operators within this case., because I am getting some undesired behavior with some of them.
I continue learning…
