What parameters can be provided to the countDocuments() method?

The countDocuments() method in MongoDB provides a way to count the number of documents in a collection that match a specified query. The correct answer highlights that it can accept both a query document and an options document.

When using countDocuments(), the query document allows you to specify criteria that filter the documents to count based on given conditions, such as matching a specific field value or applying multiple conditions with logical operators. This enables users to perform precise counts that align with their querying needs.

Additionally, the options document can include several configurations that influence how the count is performed. For example, options can include the "collation" parameter, which allows the count to be case-insensitive or locale-specific, thereby enhancing the functionality and versatility of the method to cater to specific use cases.

Thus, by accepting both a query document and an options document, countDocuments() empowers developers to efficiently obtain counts that are tailored to their specific requirements.
