Elasticsearch Training: Online Courses & On-premise Workshops
Learn & Master Elasticsearch Faster
Your Elasticsearch instructor is an active Elasticsearch engineer, developer and consultant with years of experience helping enterprise, medium and small organizations. Radu has worked with clients from 20+ different industries and is the author of Elasticsearch in Action. Here are some problems Radu Gheorghe solved for Sematext clients recently:
- Improved search relevancy using Learning to Rank
- Optimized multiple petabyte-scale clusters. Some up to 400 nodes.
- Designed Elasticsearch index and cluster architecture for dozens of clients
- Optimized log ingestion pipelines to parse and enrich 100K+ events/second
- Helped clients and DevOps teams reduce production Elasticsearch and ingestion pipeline costs by as much as 10x
Attendees come in highly motivated, making the class feel more “alive” than I expected. They constantly look for take-aways to improve their setup, from tweaking a boost to changing the sharding strategy. Their use-cases are very diverse, too, so we end up covering a lot of material.

What attendees say
Sematext was an ideal training partner for Parse.ly. We had just recently adopted Elasticsearch on a new project, and they gave us two days of solid training that was tailored to our team’s needs. The material was built atop strong foundations and moved quickly into advanced areas around querying, Lucene internals, and cluster performance. It was clear that it was all informed by real-world experience operating these systems at scale.

Not your typical by-the-book training. Radu was engaging and was a great guide in our journey through Elasticsearch.

Staff Engineer - Wayfair
I had to leave before the last class ended unfortunately. But had I been there I would have given you a mini-speech to tell you how awesome you were! ☺️
Thank you so much for being such a fantastic, patient, and effective instructor throughout this 4-day training. Personally, I appreciated the clarity and expertise in the material and the class.
I also thought the class was meticulously structured over the 4 days, each day not feeling too long, and with the right number of breaks - this made me feel like I had the capacity to learn the things planned for the day without feeling too overwhelmed. Having the course material is great for the team to revisit later.Overall, we really felt like we learned a lot. To put it in perspective, <name redacted for privacy> (who worked with <name redacted> and <name redacted>) already applied some of the lessons from the training in one of our customer throughput issues today. A big progress for the team. And, I am sure we will continue to apply in the future too – I just want you to know that you have clearly influenced us ☺️

8-hour Elasticsearch training. Join online classes.
Intro to Elasticsearch
In this course you will learn about all core Elasticsearch concepts – data, master and client nodes and their differences, sharding, replication, mapping, search relevance scoring, and so on.
Elasticsearch Operations
If you are looking to administer, tune and scale clusters, in this class you will learn everything you need to handle your Elasticsearch clusters in production – from tuning OS and JVM for performance to commits, merge policies and caches, query routing, scrolling, thread pools, and so on.
Elasticsearch for Product Searches
This 8-hour online course focuses on E-commerce or similar product search use-cases (e.g. searching for phones, books, people, blog posts). Because relevancy is important for product search: Elasticsearch shouldn’t return “phone accessories” on a query for “phone”. Other challenges might come up as well, for example dealing with relational data, providing autocomplete or did-you-mean functionality. This course provides solutions to these challenges.
