Summary
In this chapter, we' looked at the important, main topics for efficient indexing and relevant search results: How to store documents? What is the difference between the storable and searchable field? What is the analysis process? What is the impact on the relevant search results? In addition to that, we've briefly discussed some of the basic concepts of Elasticsearch that are associated with Lucene (for example, inverted index and the _source field).
In the next chapter, you'll learn about the Elasticsearch index—what mapping is, what inverted index is, the denormalized data structure—and some other concepts related to this topic.
