Lately I’ve been busy working on elasticsearch features for my company. In the process I came accross the shiny “geo search” feature. While not being that sensitive to shiny and new technologies (don’t get me wrong, I don’l like dusty ones) I still wanted to test elasticsearch geo capabilities for further adoption. The reference documentation… Read More Spice-up your application: add elasticsearch geo feature
I’ve been using Elasticsearch in production for about 1 year. The component does a very good job at indexing/searching but lacks a built-in solution for continuity of service: you can’t hold incoming write request an resume them at will. In my team, we started thinking about a home-made solution. We really wanted to keep our… Read More Safely re-index with elasticsearch

Either we invoke indexing tasks whenever we code an action that changes data or we use an… Read More Add search features to your application, try Elasticsearch part 3 : attaching indexation to events
Hi, This article is part of a whole which aims to describe how one could integrate Elasticsearch. The previous post discussed the concepts: why using a search engine?. No people learn the same way. I usually need to understand the theory and I need to start small. So I usually start by books. If there… Read More Add search features to your application, try Elasticsearch part 2 : start small
Hi all, The ultimate goal of a search engine is to provide fast, reliable, easy to use, scalable search features to a software. But before diving into complex and technical considerations we should ask ourselves why bother with a search engine. 1 – Why should my team bother with a new complex component ? Adding… Read More Add search features to your application, try Elasticsearch part 1 : the concepts
