Elasticsearch for Product Searches

Make Product Search Better

Rating1-star 1-star 1-star 1-star half-star
Our Elasticsearch training classes have a 4.74/5 rating based on 20 reviews

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. Radu Gheorghe, a seasoned Elasticsearch instructor, and consultant from Sematext, author of "Elasticsearch in Action", and frequent conference speaker will be your trainer.

What attendees say

Sematext was an ideal training partner for 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.

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 ☺️
