Introduction

Now we have set the mappings and put the data in the indices, we can search.

In this chapter, we will cover the search using different factors: sorting, highlighting, scrolling, suggesting, counting, and deleting. These actions are the core part of Elasticsearch: ultimately, everything in Elasticsearch is about serving the query and returning good-quality results.

This chapter is divided in two parts: the first part shows how to perform an API call-related search, the last part will look at two special query operators that are the basis for building complex queries in the next chapters.

All the recipes in this chapter require us to prepare and populate the required indices: the online code is available on the PacktPub website (https://www.packtpub.com/big-data-and-business-intelligence/elasticsearch-cookbook) or via GitHub (https://github.com/aparo/elasticsearch-cookbook-third-edition). There are scripts to initialize all the required data.
