As some of you know, I’m hosting an Elasticseach cluster on Azure using Windows Server virtual machines. When working as an external consultant, I always recommend my customers to host Elasticsearch on Linux. So why not follow this rule myself? Well, if shit hits the fan, I need to…
Most of you probably know my startup elmah.io [https://elmah.io]. If not, check it out and head back here when you’ve signed up 🙂 At elmah.io we index errors generated at our customers websites. Among a lot of other things, we index the user agent causing the…
I recently had the chance to cleanup an Elasticsearch mapping that I’ve been dying to refactor for some time now. The problem were a number of not_analyzed fields which really should have been analyzed, making them available for full-text search. When doing so, I encountered a problem with…
I talk to a range of customers during my work as an external consultant. It never ceases to amaze me how few who have actually considered setting up retention on their data. I know that storage is cheap these days, but most data stores handle large amounts of data poorly,…

I have been running Elasticsearch on Windows for almost two years now. As a .NET developer and general happy Windows user, choosing a known environment have some advantages. In fact Elasticsearch runs pretty smooth on Windows, but it’s no secret, that the support for running Elasticsearch on Linux has…
My pet project elmah.io [https://elmah.io/] stores every error in Elasticsearch and the search GUI contains a perfect example for doing faceted search: the errors graph in top of the search result. ![errors_per_day](https [/content/images/2013/10/errors_per_day.png] At the moment the…
In this post I will share my experiences setting up Elasticsearch in a clustered setup of virtual machines, running on Windows Azure. I use this approach for hosting Elasticsearch on my SaaS startup elmah.io [https://elmah.io]. Disclamer: this is in no way an official guide on how to…
