I have a collection of documents with a large array.
How correctly, for example, to delete several elements of an array, change the order (sort) or add a new element to the end? Need to reload an array?

Use operations to work with arrays. With the help of them you can modify the array in different ways.

If the array is so large that the search operations of the element take a long time, then you can make an index on the array.
