Topics:

• Write and execute metric and bucket aggregations
• Write and execute aggregations that contain sub-aggregations
• Write and execute pipeline aggregations

The folder scenarios-to-go contains a collection of docker-compose files to spin up simple Elastic clusters, useful to practice with Elasticsearch.

Let's add more docker-compose files!

• update the compose files in v7.4 to the latest version of the stack (v7.9, as of Sep 28)
• an Elasticsearch cluster synced with a MySQL db via Logstash
• a sample application that is sending metrics/logs to a cluster via Beats
• a sample application that is sending metrics/logs to a cluster using the Elastic Agent
• a sample application that is sending traces to a cluster using the Elastic APM tools
• a cluster with the security features enabled
• ...

Add a README.md to each scenarios-to-go subfolders, to describe the architecture and explain how to use the scenario.
Ideally, there should be two sections: "Overview" and "How to use this".

As of 17 Oct 2022, the version of Elasticsearch used for the Engineer certification exam is v8.1.

Most of the exercises currently available in the exercises folder were written for v6.5. These exercises should be rewritten to be compliant with v8.1.

Topics:

• Write and execute a search query for terms and/or phrases in one or more fields of an index
• Write and execute a search query that is a Boolean combination of multiple queries and filters
• Highlight the search terms in the response of a query
• Sort the results of a query by a given set of requirements
• Implement pagination of the results of a search query
• Use the scroll API to retrieve large numbers of results
• Apply fuzzy matching to a query
• Define and use a search template
• Write and execute a query that searches across multiple clusters

Thanks a lot for your exercizes, very useful to me while i am preparing for the exam.

Do you have plans to add more examples to cover the other objectives?

Either way thanks a lot.

I was working through these, but am wondering what the answer would be for the 2nd part of this question:

# Run the next queries on the kibana_sample_data_ecommerce` index

• search for documents with the day_of_week field containing the string "Monday"
• As above, but sort the results by the products.base_price field in descending order, picking the lowest value of the array`

I was working towards a nested query, but I then saw in 7.2 the sample ecommerce does not contain nested objects, so I was kinda clueless how to get this..

As of Sep 28, the version of Elasticsearch used for the Engineer certification exam is v7.2.

Most of the exercises currently available in the exercises folder were written for v6.5. These exercises should be rewritten to be compliant with v7.2.
