A while ago I was working on a prototype to search larger structured documents using Elasticsearch. We were only interested to make the text searchable, with an option to search all the text and some seperate fields. Elasticsearch is of course a perfect solution for this with the
_all field and the possiblility to search single or multiple fields.

I started a blog on blogspot in 2009, just to have something to put my thoughts on. In the beginning I did not blog regularly with 17 posts from 2009 to 2011 but wrote my most popular post so far when it comes to total visits on using Akka from Java. When starting as an independent developer in 2012 it was clear for me that I wanted to use blogging for my marketing because it's a great way for me: When writing posts I can learn a lot about different topics I am interested in.

I am currently working with a team starting a new project based on Lucene. While most of the time I would argue on using either Solr or Elasticsearch instead of plain Lucene it was a conscious decision. In this post I am compiling some sources for learning Lucene – I hope you will find them helpful or you can hint what sources I missed.

This is something I wanted to write down for years but never got down to completing the post. It can help you a lot with certain Elasticsearch setups by answering two questions using the slow log.

When scaling Logstash it is common to add a message broker that is used to temporarily buffer incoming messages before they are being processed by one or more Logstash nodes. Data is pushed to the brokers either through a shipper like Beaver that reads logfiles and sends each event to the broker. Alternatively the application can send the log events directly using something like a Log4j appender.
