Hello!
I am very new in elasticsearch and would like to know how to learn more about it. Like PDF, eBook, vídeo/on line class, books...? Something made for begginers. Thanks
Welcome 
Check out https://www.elastic.co/guide/en/elasticsearch/guide/2.x/index.html, it goes from first principles into Elasticsearch
Man,
Thank you for answer.
But, I'm breaking my head to install it, even following the elasticsearch website.
If you know about some video to show how to do it, please, let me know.
I'll keep trying...
thank you.
