Introduction

Notes:

• You can only run the aggregation pipeline on collections created in the CMS or with the Data Collections API. They cannot be used on Wix app collections or external collections.
• The values you provide for each filter field must adhere to that field's data type. For example, when filtering by a field whose type is Date and Time, use an object in the following format: "someDateAndTimeFieldKey": { "$date": "YYYY-MM-DDTHH:mm:ss.sssZ"}. Learn more about data types in Wix Data.
