Elasticsearch Training

Elasticsearch is a distributed search and analytics engine that sits behind site search, product catalogues, log analytics and security monitoring in many companies. Together with Kibana and ingestion tools it forms the Elastic Stack, used by development, operations and security teams.

This course starts with how Elasticsearch stores and indexes documents using inverted indexes, and why mappings and analysers matter so much for relevance. You will learn to index data, write queries in the Query DSL, tune relevance, and run aggregations for analytics. The newer ES|QL piped query language is introduced alongside. Kibana modules cover exploration and dashboards, and ingestion modules cover bringing in logs and metrics. The operations part explains shards and replicas, cluster health, index lifecycle management, snapshots, performance, and the essential security settings, plus a first look at semantic and vector search.

Elastic runs its own hands-on certification exams for engineers, which are optional and external to this course. The course topics overlap with the Elastic Certified Engineer exam, but we do not claim to cover the exam syllabus exhaustively.
