Book announcement: ElasticSearch Quick Start

About 18 months ago I was working on a customer project in which ElasticSearch was a major component. While I had quite a lot of prior experience with ElasticSearch something at this time got me thinking about the lack of good, simple, tutorials for helping developers new to ElasticSearch get started. So, one night I sat down and I wrote such a tutorial, a blog post titled "ElasticSearch 101". Since it was first published it has accounted for 50-70% of the total traffic to my site and it has received a lot of positive feedback in the comments.
