MongoDB Query Language (MQL) Element Query Operators

Element query operators test for the presence or type of fields within documents. These operators enable you to filter documents based on whether specific fields exist, match certain data types, or have particular characteristics, useful for schema validation and flexible querying.

$exists

The $exists operator retrieves documents that contain the specified field in their document structure.

$type

The $type operator retrieves documents if the chosen field is of the specified type.
