Querying ElasticSearch – A Tutorial and Guide by Rufus Pollock.
From the post:
ElasticSearch is a great open-source search tool that’s built on Lucene (like SOLR) but is natively JSON + RESTful. Its been used quite a bit at the Open Knowledge Foundation over the last few years. Plus, as its easy to setup locally its an attractive option for digging into data on your local machine.
While its general interface is pretty natural, I must confess I’ve sometimes struggled to find my way around ElasticSearch’s powerful, but also quite complex, query system and the associated JSON-based “query DSL” (domain specific language).
This post therefore provides a simple introduction and guide to querying ElasticSearch that provides a short overview of how it all works together with a good set of examples of some of the most standard queries.

This is a very nice introduction to ElasticSearch.
