Everything You Always Wanted to Know About Nested * But Were Afraid to Ask

The Westwing mission is to inspire and make every home a beautiful home. We offer the latest trends in home décor and furnishing products, and want to help our customers to easily find the ideal fit for their home. A good search experience is fundamental for our business. It is our challenge to provide it.

Faceting, filtering and sorting are well established standards for e-commerce websites, since they allow to the user to navigate through the otherwise overwhelming amount of goods and products. Of course, ElasticSearch provides us with all of the machinery to efficiently implement these standards. With a flat data structure, this is extremely simple. Unfortunately, a flat data structure isn’t always sufficient.

In some cases, nested data structures become unavoidable: products come in different sizes, prices, colours etc. Dealing with this level of detail in the proper way makes it more difficult to query, sort and aggregate data. In this talk I will guide you through the additional conundrums that come with nested fields and show how to solve them. I will review how we implemented the basic building blocks of faceting, filtering and sorting, using nested queries, nested aggregations, nested sorting and inner hits.


This talk is centered around building real-time and lightening responsive news search engine. From streaming data processing to system architecture, all bits and pieces will be covered. Specially in case of news articles streaming in the system, challenges and whole ecosystems of aggregation to scoring algorithm will be introduced. Realisation of plug and play micro-service architecture will be another focus of this talk so that in the end audience will see how complex but fun is building news search engine. This talk will be accompanied by live demo showing how to create one focused news feed using Cliqz News Technology.
