Hi, a client is asking for this certifications, but it seems that they are not part of yours certifications:

-Elasticsearch advanced data modeling.  
-Elasticsearch Developer.

Googling I found this document that seems legit:  
[https://www.seacom.it/wp-content/uploads/2017/04/Advanced.Elasticsearch-.Data\_.Modeling.Outline.pdf](https://www.seacom.it/wp-content/uploads/2017/04/Advanced.Elasticsearch-.Data_.Modeling.Outline.pdf)

Are these courses that you teach?

Hello Daniel,

This is a very old course (2017) that we used to teach.

We now updated the content and we teach (and certify) for a Elasticsearch Engineer course now: [Elasticsearch Engineer | Elastic](https://www.elastic.co/de/training/elasticsearch-engineer)

The relevant topics from the course you mentioned are in this course
