Since we did not configure anything, the name of our instance will be a random 7 letters string:. We already have a clean Elasticsearch instance initialized and running.

The first thing we are going to do is to add documents and to retrieve them. Also, documents are added to indices, and documents have a type.

We are adding now to the index named accounts a document of type person having the id 1; since the index does not exist yet, Elasticsearch will automatically create it. After the operation succeeds, the document will be changed. So far, we did retrieve documents by id, but we did not do searches. In this result we can see the matching documents and also some metadata like the total number of results for the query.

Before running the searches, try to figure out by yourself what documents will be retrieved the response comes after the command:. This search will not return any document.

As an exercise for the reader, try to do:. This last example brings a related question: The answer is yes: Try this:. Additionally to searching in one index, we can search in multiple indices at the same time by providing a comma-separated list of indices names, and the same can be done for types.

There are more options: As an exercise for the reader, add documents to a second different index and do searches in both indices simultaneously.

The first step is to download the file shakespeare. Elasticsearch offers a Bulk API that allows you to perform add, delete, update and create operations in bulk, i. This file contains data ready to be ingested using this API, prepared to be indexed in an index called Shakespeare containing documents of type act, scene and line.

We will not dig deeper into the Bulk API: Since the body of this request is fairly big more than , lines , it is recommended to do this via a tool that allows to load the body of a request from a file - for instance, using curl:.

Once the data is loaded, we can start doing some searches. In the previous section we did the searches passing the query in the URL. The format for searches is pretty straight forward.

A lot of different types of searches are available: Next we plan on improving them: This is a long-term project but you should notice a steady improvement in the documentation over time. We welcome feedback, suggestions and pull-requests!

Docs! Docs! Docs

All of our projects will be using the same framework to provide their documentation. We have chosen to use AsciiDoc as our markup language, because it is easy to read, very expressive and, via DocBook, gives us the assurance that we don't have any bad links.

Also, because we build all docs from each project together, we can ensure that cross-document links work and continue to work when edits are made later on. It was important for us to find the right partner for this book: O'Reilly has a long track record of supporting the open-source world and we are thrilled to be working with them on this important project.

While our reference documentation is intended to explain how to use a particular API and what parameters it accepts, the book will focus on how to approach and solve problems: It will be suitable for beginners who know nothing about search, but will have enough meat in it to satisfy the more experienced as well.

The book will be freely available online in HTML format both on our website and on O'Reilly's site and, when finished, will be available to purchase in hard copy from O'Reilly. Most of the beginner headache with the DSL come from this:. Types are deprecated , you can only use one in Elasticsearch 6.
