Have you ever thought how great it would be if you could filter, transform, aggregate, search and enrich billions of Elasticsearch records in a single, readable line?
Well, that's the promise of ESQL. It's the modern piped query language that's at the heart of this book. To get started, you just need to pick a source, chain each step with a pipe, and read your query from top to bottom like a sentence. The amount of JSON needed for this kind of work is much less than it used to be. This book is for data analysts, security professionals, and developers who work with large datasets, and it takes you from your very first query to production-ready integration. You'll be shaping and summarising data, cleaning messy logs, joining across indices, ranking results by relevance, and building semantic and hybrid AI-powered search.
Plus, you'll be visualising your findings in Kibana dashboards and running ESQL directly from Python, JavaScript, and automation.This book is all about getting you hands-on with real-life examples in an online retail setting, so you can put each concept into practice and get writing ESQL straight away.
Key Learnings
- Write piped ESQL queries that can filter, transform, and aggregate in one readable flow.
- Retrieve rows and columns with precise filtering and shaping.
- Compute new columns using math, string, date, and conditional functions inside queries.
- Summarise millions of rows into totals, averages, and trends using STATS.
- Clean multi-value fields and parse unstructured logs into typed, query-ready columns.
- Correlate data across indices using ENRICH policies and LOOKUP JOIN.
- Rank results with full-text MATCH and relevance scoring.
- Build semantic, hybrid, and AI-assisted search with vectors and inference.
- Turn queries into Kibana charts and interactive dashboards.
- Run ESQL from Python, JavaScript, with further automation too.

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.

To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
