Chapter 4: Exploring Search Capabilities
Now that we have set the mappings and put the data inside the indices, we can start exploring the search capabilities of Elasticsearch. In this chapter, we will cover how to search using different factors: sorting, highlighting, scrolling, suggesting, counting, and deleting.

- Executing a search
