Summary
In this chapter, we learned about Elasticsearch architecture and the way Elasticsearch was born. Later we got familiar with Elasticsearch APIs - Search, Indices, and Document. With the help of these APIs we learned how to add documents to Elasticsearch, how to query those documents, managing the indices. At the end of the chapter, aggregations show how to effectively search documents. We will be practicing these concepts in the next chapters with more examples.
In the next chapter, we will learn about Logstash, and how to configure Logstash for complex data types, and Logstash plugins.
