Hi All. I am new to ES and search in general. I have noticed that in the ES guide the Intro and Concepts section is conspicuously missing. Just wondering if this is a bug or if they actually haven't yet been authored. For someone new to the concepts of search it's a bit difficult to jump right into the API. This isn't really a complaint (I certainly know how difficult generating good documentation can be and the stuff that is there in reference seems thorough), it's more a question as to if anyone knows of a basic tutorial that demonstrates some of the basic features. Any pointers would be helpful, thanks! Idan ---

The best introduction to ES is not in the guide, but the home page of the project: [http://www.elasticsearch.org/](http://www.elasticsearch.org/). It is indeed somewhat strange that that information is not explicitly in the guide, but on the front page. The github page also has an identical introduction: [GitHub - elastic/elasticsearch: Free and Open, Distributed, RESTful Search Engine](https://github.com/elasticsearch/elasticsearch) -- Ivan ---
