Search recommendations are a simple way to direct users to results they might not find on their own. This instructor-led course will walk you through creating and running a simple movie recommendation system using the Elastic Stack and Spark.
Note: This course is a module of the Data Science specialization.


After exploring how the Elastic Stack can be used for recommendations, you will learn how use significant terms aggregations to find "commonly uncommon" recommendations. You will then use Graph, the perfect tool for visualizing the recommendations as you discover them. After completing this course, you will be able to use the Elastic Stack in combination with Spark to make retail-style recommendations.
