Elasticsearch: Efficient Search and Data Analysis (ELSSR)

Databases, NoSQL and Big Data

Elasticsearch is a powerful engine for full-text search and data analysis. This practical two-day course covers deployment patterns, core architecture and index design. You will learn how indexes, shards and documents work to scale search across large datasets efficiently.

During hands-on sessions you'll practice queries, aggregations and mapping strategies to tune relevance and performance. The course shows Ingest node usage, preprocessing pipelines and options for cloud and on-premise deployment and monitoring.

THIS TRAINING COURSE WILL HELP YOU:

  • Understand Elasticsearch architecture, indexes, shards and documents
  • Compose effective Full Text, Term and Query String queries
  • Use filters and aggregations to optimize search and analysis
  • Operate Elasticsearch on cloud and on-premise environments
  • Use Ingest node to preprocess and enrich data before indexing

WHO SHOULD ATTEND?

  • Developers implementing full-text search and analytics
  • Data architects designing search and analytics systems
  • IT professionals deploying and managing Elasticsearch
  • Data analysts performing advanced queries and analysis
