Building Search App for Public Mailing Lists in 15 Minutes with ElasticSearch by Lukáš Vlček.
You will need the slides to follow the presentation: Building Search App for Public Mailing Lists.
Very cool if fast presentation on building an email search application with ElasticSearch.
BTW, the link to BigDesk (A tiny monitoring tool for ElasticSearch clusters) is incorrect. Try: https://github.com/lukas-vlcek/bigdesk.
