Hopefully this little tutorial was a good demonstration about what is possible in Elasticsearch. It is really just scratching the surface, and many features — such as suggestions, geolocation, percolation, fuzzy, and partial matching — were omitted to keep the tutorial short. But it did highlight just how easy it is to start building advanced search functionality. No configuration was needed… just add data and start searching!
It’s likely that the syntax left you confused in places, and you may have questions about how to tweak and tune various aspects. That’s fine! The rest of the book will dive into each of these issues in detail, giving you a solid understanding of how Elasticsearch works.
