MongoDB Query Language (MQL) Array Query Operators
Array query operators allow you to perform operations on array fields within your documents. These operators enable you to filter, manipulate, and analyze array data effectively, making it easier to work with complex data structures in your queries.
$all
The `$all` operator selects the documents where the value of a field is an array that contains all the specified elements.
$elemMatch
The `$elemMatch` operator matches documents that contain an array field with at least one element that matches all the specified query criteria.
$size
The `$size` operator matches any array with the specified number of elements.
