Summary
The chapter you just finished was again focused on querying. We used filters and saw what highlighting is and how to use it. We learned what are the highlighter types and how they can help us. We validated our queries and we learned how Elasticsearch can help us when it comes to sorting our results. Finally, we discussed query rewriting, what that brings us, and how we can control it.
In the next chapter, we will get back to indexation topic. We will discuss indexing complex JSON objects such as tree-like structures and indexing data that is not flat. We will prepare Elasticsearch to handle relationships between documents and we will use the Elasticsearch API to update the structure of our indices.
