WARNING: This documentation covers Elasticsearch 2.x. The 2.x versions of Elasticsearch have passed their EOL dates. If you are running a 2.x version, we strongly advise you to upgrade.

We have seen how Elasticsearch makes it easy to start developing a new application without requiring any advance planning or setup. However, it doesn’t take long before you start wanting to fine-tune the indexing and search process to better suit your particular use case. Almost all of these customizations relate to the index, and the types that it contains. In this chapter, we introduce the APIs for managing indices and type mappings, and the most important settings.
