Elasticsearch queries are great - the query DSL is very rich and keeps evolving continuously. It's hierarchical structure allows for very sophisticated queries to be written and executed, and for handy UIs to wrap it with auto-complete features, for example.

However, like with every DSL, Elasticsear...

Elasticsearch supports scripting in several places, however the most notable and useful usage of scripting is in queries. You can use Groovy scripts to run dynamic scripts on query time to perform filtering, adjust scoring or compute aggregations. Scripting support is very useful, especially since i...

A few months ago I worked on a nice proof-of-concept showing the capabilities of both the awesome NServiceBus platform (for building SOA type applications easily on .NET and monitoring them), and Elasticsearch + Kibana (for real-time analytics and visual dashboards). I never made that public and may...

In the previous tip we discussed index mappings in Elasticsearch, and how to make managing them an easier task.

But one problem still remains - in real life indexes will consist of more than just a few fields. Often times in fact they will have dozens of them. As if that's not enough, every few fiel...

No data store with secondary indexes is truly schema-less, and Elasticsearch is no different. While it doesn't require you to define your data structure up-front, it does derive a schema from your documents structure and makes decisions on how to index them based on that. In that respect, Elasticsea...

Slides for my recent talk at CodeMash titled "ElasticSearch – Distributed search and analytics on BigData made easy" are below.

Elasticsearch is a cloud-ready, super scalable search engine which is gaining a lot of popularity lately. It is mostly known for being extremely easy to setup an...

This week I had the pleasure of talking to Carl and Richard of the .NET Rocks fame. We had a great discussion on search engine libraries and search servers - where they fit in the general scheme of things, and when and how one should use them.

You can go and listen to the recording here.

A quick run...

This is the first post of what I hope will make a useful series on Elasticsearch. In this series I will share some tips and tricks I often give when working with various clients, or during courses or conference presentations.

In this post we will show-case Sense, the best Elasticsearch REST client o...

It's been almost 3 months since I last posted in this blog. It's not that I don't have what to blog about - it's the other way around, I have too many things to talk about and too little time to do so. So I thought I'll give a little sign of life!

Ever since I started freelancing (a little bit over ...

Running Elasticsearch in the cloud with Azure is fairly easy. There are several guides out there talking about how to do this, but my way of doing this is a bit different so I thought it'd be worth blogging about. I've also included discussions on some important related topics in the end.
