review feedback, sections 1-3:
1. On page 2, the text area underneath the sentence "elasticsearch will return a result in a JSON format as follows" is wrong or mislabed. As the text says earlier, Elasticsearch does not return full document bodies, only IDs, yet we show a full document body here. To be clear we should show the ES response (something omitted from the slide that this came from), which only contains the meta-data. And then show the document lookup in Couchbase (what is actually shown here).
2. Section 1.2 is missing some steps. The blog describes the need to install an "index template" and I don't see that here
3. I know they aren't consistent yet either, but I would go with the capitalization "Elasticsearch" when referring to the product. That seems to be what they are going with on their corporate site: http://www.elasticsearch.com/products/elasticsearch/
