Elasticsearch training for those that already know the basics

Advanced Elasticsearch Training

Warning: This training material has not really been designed for self guidance. It assumes an instructor will verbally explain a lot of the material.

This material also assumes that you have already covered the basics including simple queries, index mappings, relevancy scoring, and custom analysers.

See, for example, https://jamesfer.me/intro-elasticsearch-training/#1

Topics

• Nodes, shards, replicas, master nodes
• Query profiling
• Aggregations
• Nested objects
• Parent/child docs
• Field Collapsing
• Geospatial data
• Logstash
• Suggesters
• Controlling scores
• Percolators

Prerequisites

You need to install various software tools.

Requirements:

• Docker (if on OSX, Docker for Mac is recommended)
• docker-compose

Notes

There are scripts in the scripts directory that use docker-compose to create, stop and destroy an Elasticsearch + Kibana environment.

If you have previously run a different version of Elasticsearch with these scripts, especially anything before version 7.13.2 then it may be best to destroy your existing Elasticsearch data with scripts/destroy.

Create an environment with:

scripts/up

Elasticsearch should now be available on http://localhost:9200

Kibana should now be available on http://localhost:5601

Stop the environment with:

scripts/down

Data is persisted so a subsequent scripts/up will start up ES and Kibana with your data still there.

Cleanup the environment and delete all data with:

scripts/destroy
