In this 1-hour long project-based course, you will learn how to perform deep filter operations over 1, 2 and 3 relationships. You will learn how to use the “in” field lookup to create a filter inside a filter. You will discover the difference between using a comma in a filter call and nesting filters via an example, and will see the difference between the implementation of the “comma” in the filter and the exclude methods. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.
