How does the Elasticsearch work internally?

Elastic Stack Elasticsearch

Hi,

I am trying to understand how the core Elasticsearch algorithm works, especially how the inverted indexes and other data representations are created and how they are searched on query time. I was unable to find any resources online. Can you guys point me to the resources so that I can better understand the core working algorithms?

Best,
Sheharyar

Hello @Sheharyar_Khalid,

Besides the documentation, videos and Elastic training, you might find this blog helpful as a summary.
